Free and total PSA in prostatitis: blood test rates and causes of abnormalities. What you need to know about PSA for prostatitis? Dog prostate

General analysis of PSA is the determination of indicators of prostate specific antigen, the production of which is produced by the tissue of the prostate gland. The PSA protein is essential for thinning male sperm. It should be noted that a larger amount of this substance is formed by malignant neoplasms. For this reason, the analysis is used as a tumor marker in prostate cancer. In addition, absolutely any pathological process that occurs in a man's body can affect the amount of this protein produced. That is why PSA analysis for prostatitis must be carried out without fail. Thanks to him, you can identify the development of oncology or prostate adenoma. So, let us consider in more detail what the PSA analysis is for prostatitis, what are its norms, and also for what reasons there are deviations from it.

Why does the protein indicator increase?

How is the quantity of this element determined? To determine the level of protein, it is necessary to pass a free PSA test. The rate of this antigen should be no more than 4. With the presence of malignant cells in the body, protein production begins to increase significantly. For the rest, with a general PSA blood test for prostatitis, the rate will increase for the following reasons:

  • The antigen level may increase due to existing infections, which are also accompanied by an inflammatory process in the male body. In such a situation, the barrier function of the tissue is disrupted, due to which the substance gradually enters the bloodstream.
  • The PSA protein of the prostate can actively enter the bloodstream if the overgrown tissues in the presence of benign prostatic hyperplasia press on other tissues of the organ.

It should be noted that the analysis of antigen in such a disease as prostatitis reveals any deviation and disturbance in the entire work of the male body. The majority of patients with an elevated antigen count do not suffer from cancer. With a general blood test for PSA in prostatitis, the rate may increase due to surgery on the bladder or due to a biopsy of the prostate gland. In addition, the amount of antigen in the blood increases during ejaculation or after prolonged physical exertion.

When to get tested

As mentioned earlier, a PSA test is taken for prostatitis. However, this is done in other cases as well. The specialist prescribes these laboratory tests in the following situations:

  1. To watch how prostate cancer develops. Thanks to this, you can check the effectiveness of the selected treatment tactics.
  2. If there is a suspicion of a neoplasm on the prostate gland. However, this can be detected with other diagnostic methods: ultrasound, digital rectal examination, and others.
  3. For prophylaxis, antigen analysis is prescribed to patients over 40 years of age to detect an increase in protein levels.
  4. After anticancer therapy, which was carried out after diagnosis of prostate cancer. As a rule, after such treatment, experts recommend that patients undergo this examination at least once every 3 months.

Preparation for the test

In order to donate blood for PSA analysis for prostatitis, you should carefully prepare for this procedure. If you ignore this step, then the protein antigen indicator will be incorrect. For this reason, experts recommend observing the following rules:

  1. About 8 hours before blood sampling, do not eat food, and also stop drinking alcoholic beverages, strong tea, coffee and juice.
  2. It is also necessary to give up sexual intercourse about 5-7 days before blood sampling.
  3. The analysis must be taken 12-14 days after the examination of the urologist or before his visit.

If massage of the prostate gland, catheterization of the bladder, transrectal ultrasound or cystoscopy, digital rectal examination or other mechanical effect on the prostate was done, then blood is taken 2 weeks after such research methods, and if a biopsy of the prostate tissue was performed, then the analysis is submitted after 1 month after this procedure.

Deciphering the PSA analysis is carried out for about 1 day. To pass the analysis to a man, a specialist must give a referral, after which the patient is prepared, and then donates blood from a vein. Sometimes it is required to determine either the free antigen or the total indicator. This is necessary in order to more accurately diagnose the patient.

Decoding the results

We have already discussed with you what PSA analysis means for prostatitis. But how does it stand for? Antigen analysis for a given disease can be interpreted by several methods. Blood antigen levels are usually measured in nanograms per ml of blood. At the same time, some experts say that the minimum threshold for this indicator should be reduced to 2.5. Thanks to this, it will be possible to detect more diseases of the prostate gland. However, there is a risk that specialists, as a result of this test, will treat cancer that has no clinical significance. During the diagnosis, three types of protein should be considered:

  1. Free prostate specific antigen. This antigen is found in the blood, accounting for about 20% of the total PSA.
  2. A protein that is associated with A1-antichymotrypsin or A2-macroglobulin. Only the first type of antigen can be determined in the laboratory.
  3. General score for PSA analysis. This indicator includes the totality of the protein that enters the bloodstream.

PSA and prostatitis

This disease, in fact, cannot be called a malignant disease. After all, prostatitis does not even increase the likelihood of developing prostate cancer. But with the help of regular monitoring of the level of antigen, you can correctly adjust the treatment, which is aimed at combating the inflammatory process. If the antigen indicator is in the range from 4 to 10, then this may indicate the development of the following diseases:

  1. Prostatitis.
  2. Oncology of the prostate gland. In this case, the risk of diagnosing the disease increases by about 25%.
  3. Benign prostatic hyperplasia.

It should be noted that this indicator of the antigen level is called the gray zone by experts among themselves. If the protein concentration rises above 10, then the likelihood of developing oncology appears by about 67%.

Quite often, the level of common antigen is directly related to a type of prostate ailment. This analysis is often used for differential diagnosis.

How disease is defined

If the analysis was submitted and performed correctly, and the antigen level is between 45 and ten, then during the diagnosis, experts pay attention to the following protein fractions and ratios:

  1. A decrease in the concentration of free antigen increases the risk of developing cancer. This is due to the fact that malignant cells produce much more A1-atichymotrypsin.
  2. An increased concentration of free antigen, on the contrary, reduces the risk of developing cancer. Moreover, this indicator may indicate the presence of chronic prostatitis.

Other data

A general analysis for the determination of antigen in the blood for prostatitis, the price of which will differ depending on the clinic, is recommended for patients over 50 years of age, once a year. To improve the test results, additional indicators are used that allow considering the protein depending on various parameters.

During the analysis, the density of the antigen should be taken into account. Due to this, it is possible to calculate the protein concentration in relation to the size of the prostate itself, which is determined using transrectal ultrasound. Low antigen density may indicate that the main reason for its growth is hidden in the development of prostatitis.

In addition, the rate of antigens is also taken into account. It is a comparison of antigen over a certain period of time. If the indicator increases rapidly, then the specialist can diagnose the patient with acute prostatitis. This may also indicate the initial stage of oncology.

Protein control

It is possible to track the indicator of protein in the blood only with the help of the analysis, which is discussed in this article. The specialist must study the features of this test in detail. For example, as a result of recent studies, it has been proven that a disease such as prostatitis can lead to an increase in serum levels of this antigen. It is necessary to take the test even if there are no signs of an inflammatory process, and a digital rectal examination does not reveal any abnormalities.

First of all, such phenomena indicate that the prostate does not work well due to some disorders. If the analysis indicators jump sharply, then doctors in this case recommend:

  1. If the antigen level has increased significantly, then it is necessary to check for symptoms of prostatitis, as well as any genitourinary infection.
  2. After prostatitis therapy or after genitourinary infections, it is necessary to re-pass the PSA test.

Price

The price of such a test is from 600 rubles. and more. In some clinics, the patient may also pay extra for blood sampling from a vein. In order to say about a more accurate price, in any case, you will have to contact the laboratory in your clinic.

Conclusion

There is no direct evidence that prostatitis provokes prostate cancer. But the histological signs of this disease are often diagnosed by doctors during the study of cancerous tissues of the prostate gland.

The PSA protein is a prostate-specific antigen produced by the tissues of the prostate gland. This protein is required for thinning male sperm. It is worth noting that malignant neoplasms produce more of this substance. That is why PSA is used as a tumor marker for prostate cancer. At the same time, any pathological process can affect the amount of protein produced. Therefore, PSA analysis for prostatitis is mandatory. It will allow you to identify oncology or adenoma.

To determine the level of protein, a general PSA blood test is taken for prostatitis. The antigen rate is no more than 4 ng / ml. The production of this protein increases significantly with the formation of malignant cells. Otherwise, antigen production increases due to other factors:

  1. PSA levels can rise as a result of infection, which is accompanied by an inflammatory process. In this case, a violation of the barrier functions of tissues occurs, which allows the substance to gradually penetrate into the blood.
  2. Protein can more actively enter the bloodstream if overgrown tissues with benign prostatic hyperplasia begin to press on the rest of the organ tissue.

It is worth noting that PSA analysis for prostatitis allows you to identify any abnormalities and abnormalities in the work of the prostate gland. Most of the men who have an elevated antigen level do not suffer from cancer. Protein concentration can increase as a result of bladder surgery or prostate biopsy, as well as ejaculation and prolonged exertion.

Not only for prostatitis, you need to take a PSA test. Such a laboratory study is assigned:

  1. To monitor how prostate cancer is progressing. That allows you to check the effectiveness of the selected therapy.
  2. If you suspect the formation of a prostate tumor. This can happen as a result of other tests: ultrasound, rectal digital examination, and so on.
  3. For prevention. Such an analysis is prescribed for men over 40 years of age to detect an increase in PSA levels.
  4. After anticancer treatment, which was carried out after the detection of prostate cancer. After such therapy, it is recommended to undergo such an examination every 3 months.

To pass a PSA test for prostatitis, you need to carefully prepare. Otherwise, your protein readings will be incorrect. Experts recommend:

  1. Refuse to eat 8 hours before donating blood, including alcohol, coffee, tea and juice.
  2. It is worth refraining from sexual intercourse 5-7 days before the test.
  3. The analysis should be done 12-14 days after the examination by the urologist or before visiting this specialist.
  4. If prostate massage, transrectal ultrasound, bladder catheterization or cystoscopy, rectal digital examination or other mechanical effects on the prostate were performed, then the analysis should be done 2 weeks after such research methods, and after a biopsy of the prostate tissue - 1 month later.

Research is carried out in a laboratory within one day. For this, the patient needs to write a referral from the attending physician, prepare, and then donate blood from a vein. In some cases, either total PSA or free antigen is required. This is required for an accurate diagnosis.

PSA analysis for prostatitis can be interpreted in several ways. Antigen levels are usually measured in nanograms per milliliter of blood. However, some experts argue that it is necessary to lower the minimum threshold to 2.5 ng / mg. This will, of course, allow more prostate diseases to be detected. However, there is a risk that doctors, as a result of such a test, will begin to treat cancers that are clinically irrelevant. When carrying out diagnostics, only three forms of protein are taken into account:

  1. Prostatic free specific antigen. It is found in the blood and accounts for only 20% of the total PSA level.
  2. Protein associated with a2-macroglobulin or a1-antichymotrypsin. Only the latter type of antigen can be determined in the laboratory.
  3. The total PSA is the aggregate of proteins that enter the bloodstream.

Prostatitis, in fact, is not a malignant disease. After all, it does not even increase the likelihood of developing cancer of the gland. However, regular monitoring of the PSA level allows the specialist to correctly adjust the therapy aimed at eliminating the inflammatory process.

If the concentration of antigen is from 4 to 10 ng / ml, then this may indicate the development of the following ailments:

  • prostatitis;
  • benign prostatic hyperplasia;
  • oncology of the prostate, in this case, the risk of diagnosing this disease increases by 25%.

It is worth noting that such an indicator of the PSA level is called the gray zone by experts. If the concentration of antigen increases by more than 10 ng / ml, then the likelihood of developing an oncological process increases by about 67%.

Often, the level of total PSA directly depends on the type of prostate ailment. This analysis is often used for differential diagnosis.

If the PSA general blood test for prostatitis is performed correctly, and the protein level is at least 4 ng / ml and not more than 10 ng / ml, then when making a diagnosis, doctors look at the following protein fractions and their ratios:

  1. A decrease in the concentration of free antigen increases the risk of developing cancer. This is due to the fact that malignant cells produce a large amount of a1-atichymotrypsin. This increases the protein concentration in bound form.
  2. An increase in the concentration of free antigen, on the contrary, reduces the risk of developing oncology. Moreover, such an indicator may indicate the presence of chronic prostatitis.

A general PSA blood test for prostatitis, the cost of which is specified at the clinic, is recommended for men over the age of 50 every year. At the same time, to improve the test, specialists have introduced additional indicators that allow the protein to be considered in accordance with various parameters.

The analysis takes into account the density of the PSA. This allows calculations of the concentration of antigen in relation to the size of the gland itself, which are determined by transrectal ultrasound. Low protein density may indicate that the main reason for its growth lies in the development of prostatitis.

The PSA rate is also taken into account. This is the comparison of antigen over specific periods of time. If the indicator increases rapidly, then the doctor can diagnose acute prostatitis or the initial stage of cancer.

Only a general PSA blood test for prostatitis allows you to track the protein level. The features of this test should be known for sure by a specialist. For example, recent studies have shown that it is prostatitis that can lead to an increase in serum antigen levels. The test should be taken even in cases where there are no signs of inflammation and the digital rectal examination did not reveal any abnormalities, and the rate of increase in PSA concentration has increased.

Such phenomena primarily indicate that the main organ of the reproductive system does not perform well its functions due to certain disorders. If there are sharp jumps in indicators, then experts recommend:

  1. If the protein level has increased significantly, then it is worth checking for signs of prostatitis, as well as a genitourinary infection.
  2. After treatment of prostatitis or genitourinary infection, a second PSA test should be taken.

Even if prostatitis has not been diagnosed, it is still worth doing another antigen test. If protein levels remain elevated, your doctor may order a biopsy. This will make it possible to either exclude or confirm the development of oncology.

How much does a PSA test for prostatitis cost? The price of such a test is from 600 rubles and more. At the same time, in some clinics, the patient must additionally pay for taking blood from a vein. The exact price can be checked in the laboratory.

It is worth noting that there is no direct evidence that prostatitis leads to prostate cancer. Malignant cells are not always formed. However, the histological signs of prostatitis are often found by specialists precisely in the study of cancerous tissues of the prostate. Therefore, a blood test for the amount of PSA should be carried out regularly.

Prostate-specific antigen or PSA protein is produced by the tissues of the prostate gland and is required for sperm liquefaction. Since malignant cells produce more of this protein, it is called a tumor marker for prostate cancer. However, any pathological processes in the prostate gland can affect the amount of protein that enters the blood. Therefore, a blood test reveals an increased concentration of PSA in the prostate or adenoma.

Normally, the secretory epithelium of the prostate secretes so much protein that its blood level does not exceed 4 ng / ml. However, only with malignant degeneration of cells, PSA production increases. In other cases, the growth of the indicator occurs under the influence of other factors:

  1. In benign prostatic hyperplasia, the overgrown tissues press on the normal tissues of the organ, as a result of which the protein more actively enters the bloodstream.
  2. PSA levels in the blood increase as infections and subsequent inflammation disrupt the barrier functions of tissues and the substance enters the vessels.

The PSA level is designed to detect any abnormalities in the function of the prostate gland. Most men with elevated protein levels do not have cancer. PSA concentration increases with prolonged physical activity, after ejaculation, recent prostate biopsy, or bladder surgery.

Prostate PSA test results are interpreted in different ways. Protein concentration is measured in nanograms per milliliter of blood. Some scientists believe that the minimum threshold should be lowered to 2.5 ng / ml in order to detect more cases of prostatitis and other diseases. However, this can lead to the treatment of cancers that are not clinically significant.

When diagnosing prostatitis, look at three different types of PSA:

  1. Free prostate specific antigen is only 20% of the total PSA that is in the blood.
  2. PSA associated with a1-antichymotrypsin (ACT) or a2-macroglobulin. But only the protein associated with ACT can be determined in the laboratory.
  3. The total PSA level is the total amount of protein that enters the bloodstream.

Prostatitis is not malignant and does not increase the likelihood of prostate cancer. But tracking PSA results helps the doctor adjust the process of treating the inflammatory process.

The total prostate-specific antigen at the level of 4-10 ng / ml may indicate the following diseases:

  • prostate cancer (the risk of its diagnosis increases by 25%);
  • benign prostatic hyperplasia;
  • prostatitis.

This amount of PSA is often referred to by diagnosticians as the "gray area", since values ​​exceeding 10.0 ng / ml mean a 67% increased likelihood of an oncological process.

The level of free PSA directly depends on the type of prostate disease and is used for differential diagnosis. When the total PSA level exceeds 4 ng / ml but less than 10 ng / ml, doctors look at the following ratio of protein fractions:

  • a decrease in the level of free PSA increases the risk of prostate cancer, since malignant cells produce more α1-antichymotrypsin, which increases the concentration of the protein in the bound form;
  • an increase in free PSA levels lowers the risk of cancer, but may indicate chronic prostatitis.

Additional indicators for PSA analysis in inflammation of the prostate

PSA density involves the calculation of antigen levels in relation to the size of the gland determined during transrectal ultrasound. A low protein density indicates that prostatitis is the cause of the increase in protein concentration.

The rate of increase in PSA is a comparison of protein levels over a period of time, such as a year. It is believed that a rapid increase in PSA concentration indicates the development of acute prostatitis or indicates cancer.

Recent studies have shown that prostatitis can lead to a spike in serum PSA levels. Men in whom digital rectal examination showed no signs of abnormality, but who have a high concentration and a high rate of increase in PSA levels, should be retested, despite the absence of symptoms of the inflammatory process.

An increase in PSA levels always means that the work of the main organ of the male reproductive system is disrupted. Fixing sharp jumps in the values ​​of the indicator, doctors advise:

  • with a significant increase in the level of protein, it is necessary to check for the presence of a genitourinary infection or symptoms of prostatitis;
  • if infection or prostatitis is detected, PSA analysis should be repeated after treatment.

Even if prostatitis has not been diagnosed, it is advisable to donate blood for a specific prostate antigen a second time. If the level is elevated, a prostate biopsy is done to rule out or confirm cancer.

There is no direct evidence that prostatitis can lead to prostate cancer. However, its histological signs are often found in the study of malignant prostate tissue. Iron removed due to cancer may show signs of focal inflammation in patients who have not complained of prostatitis symptoms such as pelvic pain and painful urination.

Inflammation is present in benign prostatic hyperplasia, as the enlargement of the gland causes small tears in the tubules that allow secretions to leak into the tissue and cause prostatitis. Thus, detecting PSA levels serves as the first step in the prevention and diagnosis of more serious diseases.

It has been proven that a high PSA level in prostate cancer inhibits tumor development. A negative relationship was also found between chronic prostatitis and the likelihood of developing cancer. PSA concentration is usually increased in patients with chronic prostatitis.

This inflammatory process stimulates the flow of blood saturated with immunoglobulins (immune cells) to the prostate gland. It is these antibodies that are capable of destroying the first malignant cells in the prostate and inhibiting tumor growth.

After 40 years, any symptoms of prostatitis, such as pain in the lower back, groin, sacrum, painful urination and ejaculation, discharge of blood from the urethra with semen and urine, are the basis for testing for infections and cancer. Chronic prostatitis can develop against the background of benign and malignant neoplasms.

Acute inflammation of the prostate and cancer usually cause a significant excess of the norm. Chronic inflammation is characterized by mild increases in PSA levels. In this case, taking antibiotics lowers the protein concentration. However, a drop to 5 nl / ml does not always indicate cancer, and doctors recommend taking the test six months later.

The PSA level significantly decreases after prostatectomy to 0.2-0.3 nl / ml, and its subsequent increase indicates a biochemical recurrence of prostate cancer, requiring further examination and treatment.

What is PSA? Prostate-specific antigen (PSA) is a special protein that is formed in the male body exclusively by the tissues of the prostate gland, which performs the function of dissolving sperm at the time of ejaculation. The accumulation of PSA in prostatitis in the blood of a male representative directly reflects his age and prostate volume. That is, the larger the prostate gland, the higher the PSA grade. Therefore, it is very important for any man to periodically undergo a PSA examination to determine its amount in the body.

An increased PSA density usually indicates a dangerous disease of the prostate gland. The reasons for the presented pathology:

  • malignant neoplasm, that is, cancer;
  • adenoma of prostatitis;
  • the process of inflammation that develops in the prostate;
  • heart attack or coronary artery disease.

An elevated PSA index is not always caused by prostate disease. In certain situations, this symptom is not a disease. An increase in PSA is observed in such cases:

  • a course of prostate massage;
  • ejaculation;
  • carrying out the procedure for ultrasound diagnostics of male organs;
  • biopsy of the prostate gland;
  • surgical intervention.

In such situations, PSA can rise. Therefore, before going through this study, you should consider such points. After all, the level of PSA in the blood will be atypical.

A specialist prescribes a blood test for the amount of prostate-specific antigen in such cases:

  • checking the effectiveness of the therapy for cancer;
  • to exclude a malignant tumor, an analysis is made for prostate cancer;
  • as a result of radical therapy of a patient diagnosed with prostate cancer;
  • for the prevention of men 40 years of age and above.

The analysis of the material on the PSA gives a 100% error-free result. Therefore, it is possible to identify the inflammatory process of the prostate and more serious diseases rather quickly, in the early stages of development.

How to decipher the normal state of protein in a man's blood? The following PSA indicators are considered the norm, depending on age:

  • in young men from 20 to 25 years old, the result should be no more than 2.5 ng / ml;
  • age 25-45 requires PSA 3 ng / ml;
  • in men from 45 to 65 years old - no more than 3.5 ng / ml;
  • older age - the result should not go beyond the PSA range of 4 ng / ml.

That is, if the test result is not higher than 4 ng / ml, this is a normal result, in which a malignant neoplasm is excluded.

Adenoma is an age-related disease in which the prostate gland enlarges. As a result, it ceases to perform its functions qualitatively, which leads to the development of inflammation or infectious diseases of the genitourinary system. Adenoma is not considered a fatal disease, but, nevertheless, significantly impairs the quality of normal life.
In order to detect the disease, you should be tested for the level of PSA in the blood. Before the study, doctors do not recommend eating food for 8 hours, and also refraining from intimacy for 2 weeks.
A PSA of 20 to 40 ng / ml indicates that a man is developing this disease. When this indicator is exceeded, the patient is likely to develop a malignant formation.
PSA levels in prostate adenoma need to be monitored periodically. They should not increase by more than 0.75 ng / ml per year. A more dynamic increase indicates the development of prostate cancer.
What does this indicator mean? The PSA level in prostate adenoma helps the specialist to prescribe the most effective and safe treatment for each individual case.

Prostatitis is a disease in which inflammation occurs in the prostate gland. This disease affects the PSA level, even if there are no visible changes in the man's body.
Starting effective treatment, the indicator of prostate-specific antigen gradually returns to normal - after about 4 weeks. What does a high PSA reading in prostatitis after therapy indicate? An increased rate can only indicate the development of prostate cancer. Therefore, after undergoing treatment for prostatitis, it is required to pass this PSA general blood test for acute prostatitis again in a month. Chronic prostatitis requires an indicator check every three months.

A significant increase in PSA levels indicates that the man has a malignant tumor of the prostate. If the mark reaches more than 8-10 ng / ml, an active inflammatory process occurs. The prostate gland requires additional research.
There are cases when the PSA values ​​in the blood in prostate cancer are too high - 80-100 ng / ml. With this value, prostate cancer is accurately determined, despite the fact that a man may feel quite well. If an increase in prostate-specific antigen is observed more than 100 ng / ml, an effective, potent therapy is urgently required.

How to reduce this indicator with folk remedies? You can lower your PSA level on your own, without the use of medications. To do this, you should eat food that helps to relieve the inflammatory process in the prostate gland, namely:

  1. Lean poultry helps to inhibit the process of enlarging the prostate.
  2. Fatty fish. Preference should be given to such species as tuna, salmon, herring.
  3. Dark berries and grapes. They prevent the oxidation of certain tissues, organs and glands, including the prostate.
  4. Eating tomatoes. This vegetable performs the protective function of the tissues of organs and glands, thanks to its constituents. Watermelons and apricots have the same property.
  5. Freshly squeezed pomegranate juice. It prevents the accumulation of cancer cells in the prostate gland, thereby reducing the amount of protein in the blood. It is required to consume at least 1 glass of pomegranate juice daily.

Men will also benefit from using a variety of dietary supplements. Their advantage is the complete absence of contraindications and side effects.

What should a man do with high PSA? If a man has a large amount of this protein as a result of an analysis of PSA levels in his blood, additional research is required to identify cancers and inflammatory processes.
In order to lower protein levels, the following medications should be taken:

  1. Aspirin and other non-steroidal anti-inflammatory drugs. Medicines of this group thin the blood, while decreasing the PSA level. The maximum effect is observed in nonsmoking men, even with prostate cancer. In addition to their blood thinning function, non-steroidal anti-inflammatory drugs help to improve the functioning of the cardiovascular system.
  2. Cholesterol-lowering drugs. Taking them regularly for a long period helps to exclude an increase in PSA.
  3. Medicines to improve the functioning of the cardiovascular system.

That is, it is not necessary to use drugs to lower PSA. It is enough just to normalize the work of the cardiovascular system.
You can also reduce PSA, which was found together with diseases of the prostate gland, in the following ways:

  • cryotherapy;
  • thermotherapy;
  • microwave treatment;
  • laser coagulation;
  • urethral resection.

These methods of affecting the prostate gland contribute to the removal of a malignant tumor and the elimination of the inflammatory process through the urethra.

In order to maintain the PSA level in the normal range, that is, not to exceed the 4 ng / ml mark, preventive measures are required. They should be aimed at excluding possible inflammation and enlargement of the prostate gland. To do this, you should adhere to the following rules:

  1. Timely conduct effective therapy in the event of infectious and viral diseases.
  2. Elimination of intestinal disorders. Effectively affect the elimination of anal fissures, hemorrhoids and other diseases.
  3. Intimacy should be only with a constant partner. Promiscuous intercourse increases the risk of sexually transmitted diseases, which lead to inflammation of the prostate.
  4. Observe the rules of personal hygiene, which will eliminate the risk of developing infectious diseases.
  5. Give up addictions. Excessive drinking and smoking negatively affects men's health.
  6. Physical exercises. Poor physical activity leads to congestion of the small pelvis.
  7. Proper nutrition. Eating healthy foods helps to boost immunity.

You should also not forget about adherence to the daily regimen, which will ensure a high-quality distribution of activity during the day and good rest.

The goal of medicine today is not only to cure patients from various pathologies, but also to prevent the onset of the disease at the initial stages, when therapy can still give positive results. Preventive measures are especially necessary when the body is prone to oncopathologies, since the diagnosis of the disease in the later stages most often ends in tragedy.

PSA blood test is a simple procedure recommended for all patients with prostate diseases

Malignant lesion of the prostate gland is one of the most common forms of cancer in men. The lack of diagnosis and therapy in the early stages is a fairly common phenomenon, since this disease at the beginning of its development is not accompanied by special symptoms. The study of blood parameters for prostate-specific antigen (PSA) is an important diagnostic measure to help identify pathological changes in the prostate.

PSA is a peptide protein synthesized in the male body by prostate cells. It belongs to the components of semen and reduces the viscosity of the semen. If this does not happen, fertilization does not take place, since the movement of sperm is difficult. Prostate-specific antigen is the most important substance necessary for conception to take place.

PSA protein is one of the factors that ensure the free movement of sperm

PSA indicators are necessary to detect benign hyperplasias, prostatitis and cancer.

A general PSA blood test for prostatitis is often characterized by a slight increase in indicators. In case of malignant pathology, the level of values ​​exceeds the permissible several times. Deviations in indicators are associated with excessive release of this substance in various disorders developing in the prostate, therefore, the PSA analysis, which must be taken for prostatitis, will be considered correct in the absence of injuries, even small ones.

The PSA rate (ng / ml) depends on a number of factors, which include age and some other features. So, for young men, the values ​​should not exceed 1.5. In adulthood (from 50 years old), the norm is 3.5, in the elderly - 6.5.

Only a doctor should draw conclusions about the results of the analysis, correlating them with other information about the patient.

Indicator levels increase significantly in the following cases:

  1. If the marker reaches a value of 10, most often this indicates a benign neoplasm or adenoma.
  2. When exceeding up to 30, the suspicion falls on the presence of a pathological process.
  3. A value over 100 indicates prostate cancer.

The PSA level in uncomplicated prostatitis is about 7 ng / ml.

A blood test for prostatitis will be informative only if properly prepared. In case of violation of the basic recommendations of the doctor, most often the study of the level of antigen in the blood will lead to overestimated results, which will lead to the need for further diagnosis. How to donate blood for PSA correctly?

A prerequisite in preparation for the analysis is abstinence from sexual intercourse

The amount of antigen is directly related to the stimulation of the prostate. Changes in indicators are observed after massage, cycling or ejaculation. That is why when donating blood for prostatitis, you should refrain from sexual activity for a week. Two days is the minimum period of sexual rest necessary to obtain the correct result.

If a man underwent gland stimulation, cystoscopic examinations, prostate massage courses the day before, the analysis must be passed in two weeks.

This period is necessary to normalize the level of antigen in the blood. After the biopsy, a general PSA blood test should be performed, prescribed for prostatitis, after a month. The norm for the frequency of the study when monitoring the results of treatment is once every three months.

Drinking alcohol can falsely overestimate PSA test results

In addition to sexual rest, before donating blood, you should reduce the use of heavy foods, remove fried and fatty foods from the menu, and give up alcohol. Smoking must be excluded two hours before the analysis. The study of the level of antigen in the blood is carried out on an empty stomach, but drinking water is allowed. It is advisable to avoid stress and physical activity for a week.

After donating blood, sexual rest can be interrupted, unless the doctor has recommended otherwise. If a man had previously undergone surgery to remove the gland, the normal result should be 0. When determining other values, one should suspect the presence of a metastatic process that requires immediate diagnosis.

The physician should pay special attention to the PSA level in patients after prostatectomy.

Invalid values

A PSA blood test can show false results in the following cases:

  • trauma in the perineum with damage to the epithelium of the prostate;
  • chronic prostatitis, accompanied by a prolonged inflammatory process with cell death;
  • hyperplasia of the gland of a benign nature in middle-aged men (values ​​increased slightly);
  • violation of microcirculation in the gland, which leads to the death of tissues as a result of a deficiency of oxygen, vitamins and microelements;

Microcirculation disorder occurs in the smallest vessels of the circulatory system - arterioles and venules

If there was no sexual rest before taking the test, you should notify the doctor about this. In such a situation, studies, including a general blood test, prescribed for prostatitis, should be postponed for some time. With long-term use of certain drugs, the prostatic antigen may increase. This is especially true for drugs containing reductase inhibitors prescribed for the treatment of prostate adenoma.

To correctly interpret the PSA level, the patient must warn the doctor about the medications he is taking.

Additional Information

There are special situations where testing by urologists is not recommended. These include:

  • food poisoning, intestinal infection, accompanied by vomiting, diarrhea and lack of appetite;
  • temperature rise over 37 degrees Celsius;
  • viral infection, bronchitis.

Exacerbation of the chronic form of prostatitis is not a contraindication for the study.

All of the above restrictions should be taken into account, especially in private laboratories, in which tests are often carried out, despite the well-being of patients.

To make an accurate diagnosis, the patient is prescribed additional examinations

To date, there are cases of diagnosing a malignant pathology of the prostate, in which PSA values ​​are within the normal range, which indicates the need for a set of measures to detect cancer. Diagnostics should include ultrasound (ultrasound), computed tomography (CT), biopsy, transrectal examination, dynamics of PSA values.

If the level of values ​​is exceeded by 0.74 ng / ml during the year, pathological changes in the prostate should be suspected. A neoplasm in the gland is often accompanied by leukocytosis and an increase in the erythrocyte sedimentation rate (ESR), since tumors can cause inflammation, to which the immune system reacts, so a general blood test is also necessary.

If prostate cancer is suspected, a detailed antigen test is prescribed, in which special attention should be paid to the proportion of PSA in relation to the substance associated with antichymotrypsin. If an increase in both values ​​is detected, there is a possibility of the presence of a malignant tumor.

If a malignant pathology is suspected, a biopsy of the prostate gland is prescribed for taking material for cytological examination

It is necessary to study the density of the PSA, which takes into account the size of the gland, which is established using ultrasound. An increase in antigen density values ​​is a sign of a pathological process. A biopsy is ordered after high PSA values ​​and an increase in the volume of the gland are detected.

Many men, in whose analyzes revealed an increase in PSA, are interested in how to reduce its values. The rates decrease naturally when prostate disease is healed. There are other ways, which include:

  1. Improving the quality of food and excluding canned food, smoked meats, fatty meats, margarine from the diet. The menu should contain vegetables, berries, fish dishes, white meat, a lot of greens. Such restrictions significantly reduce the risk of developing prostate cancer.

    Preference should be given to foods high in digestible fatty acids, vitamins, antioxidants

    The detection of increased PSA values ​​is not always a sign of prostate pathologies.

    Only a set of diagnostic measures helps to identify disorders that occur in the tissues of the prostate gland. An important point before taking an antigen test is to comply with all the recommendations of the urologist.

    You will learn more about the PSA analysis in the following video:

Prostate cancer is found in every eighth representative of the stronger sex who has crossed the 50-year mark, and 10% of such cases end in death. The early stage of the disease can be detected by studying the composition of the blood for tumor markers. PSA analysis in prostate cancer is one of the most reliable methods for diagnosing a tumor in order to eliminate it in a timely manner.

Prostate cancer and PSA

Malignant carcinoma (tumor) of the prostate gland occurs due to hormonal imbalance. The main male hormone testosterone is considered to be the "culprit" of the imbalance: its amount increases dramatically in prostate cancer. A characteristic indicator by which a disease can be detected is the PSA level.

PSA / - prostate specific antigen- This is a special enzyme that is part of the secretion (juice) of the prostate gland. The main function of PSA is to dilute the semen. Together with prostate juice, a small amount of antigen enters the bloodstream. In laboratory studies, it is used as a tissue-specific marker, that is, an increased PSA level does not necessarily indicate prostate cancer - this indicator can signal other diseases of the genitourinary system.

When is a PSA test prescribed?

1. Detection of symptoms of pathological processes in the prostate gland (frequent and difficult urination, pain in the groin and genitals, drops of blood in urine or semen, etc.)

2. Primary diagnosis in case of suspected oncology

3. Control over the course of the disease in the framework of dynamic observation

4. Evaluation of the effectiveness of therapeutic methods (prostatectomy, radiation, drug treatment, etc.)

5. Preventive examination of men of mature and old age

Normal PSA values

With age, the size of the prostate naturally increases, respectively, the concentration of prostate-specific antigen in the blood also increases.

Even a slight increase in PSA is a reason to undergo a urological examination.

Deviations from the norm

If the PSA value does not exceed 20.0 ng / ml, the patient is in the so-called gray zone: there may not be a malignant tumor, but the pathological processes in the body have already started. In this case, additional diagnostic measures are required that will reveal the cause of the changes taking place for their timely relief.

● The most likely PSA values ​​for prostate cancer start at 20.0 ng / ml.

● If the antigen level is above 50.0 ng / ml, metastatic lesions are found in two out of three subjects.

● A value of more than 100.0 ng / ml indicates almost 100% spread of metastases in the body.

To clarify the presence of oncology, a biopsy of the prostate gland is performed, which gives a comprehensive clinical picture of the disease and allows you to develop an adequate treatment regimen.

Clarification tests for suspected prostate cancer

Despite the fact that an increased PSA value may indicate the development of a malignant tumor, this marker is not exclusively cancer-specific. For a more accurate diagnosis, additional indices are calculated.

Determination of the level of free PSA

In the systemic circulation, the prostate-specific antigen is present in two variants:

1. fPSA, or free form, that is, not associated with proteins in the blood serum (approximately 1/5 of the total amount of PSA);

2. cPSA, or a linked form, is linked to glycoproteins (a-1-antichymotrypsin and a-2-macroglobulin).

The total value of both forms is the total PSA (its level is determined by analysis). If the marker is at the upper border of the "gray zone" (10-20 ng / ml), it is advisable to investigate the level of the free fraction.

Regardless of the stage of prostate cancer, tumor cells produce an increased amount of the bound antigen, therefore, a decrease in fPSA level is an alarming signal.

Also, as an additional criterion for diagnosis, the ratio of the free fraction to the total PSA is determined: if the value is less than 0.15 ng / ml, there is reason to suspect oncology.

Rate of change in total PSA

PSA levels in prostate cancer increase faster. Normally, the growth of antigen should not exceed 0.75 ng / ml per year.

PSA density

The ratio of total PSA to the size of the prostate gland helps to clarify the nature of the disease. A reading of less than 0.15 ng / mL per cubic meter of prostate indicates a benign growth. Increased rates indicate a cancerous tumor.

What can affect the accuracy of the analysis?

It is important to understand that high PSA levels and cancer do not always go hand in hand. The research result is influenced by a number of factors.

* If you are taking medications (in particular, 5-AR inhibitors used in the treatment of prostate adenoma), be sure to inform your doctor about it, as some of them directly affect the test results.

A significant increase in the level of PSA in the blood can be associated with pathologies such as:

● acute or chronic prostatitis;

● prostate adenoma;

● infectious processes;

● ischemia (anemia of the prostate gland, provoked by impaired blood circulation in the vessels);

● heart attack (tissue necrosis caused by spasm).

Rules for preparing for a blood test for PSA

1. A few days before the procedure, you need to adjust your diet. Fatty, salty and spicy foods, alcoholic beverages are strictly prohibited. It is advisable to limit the consumption of meat. Doctors recommend including more vegetables (fresh, boiled or steamed), lean soups, broths, and cereals in the diet.

2. At least 2 days before being tested, you must not expose the body to physical exertion, be nervous, have sex or masturbate.

3. Blood sampling is carried out on an empty stomach, so the last meal should be 8-12 hours before the procedure. It is allowed to drink plain water in any quantity.

4. For an hour or two before the test, smoking is prohibited.

Popular questions and answers

- What are the exact PSA values ​​for prostate cancer?

The quantitative indicators of the antigen, indicating oncology, are conditional. All experts agree that a PSA concentration of 30 ng / ml and higher clearly indicates the presence of a malignant tumor, but lower values ​​are also observed in prostate cancer.

- How is the PSA test done and how long will it take to get the results?

For research, take blood from a vein in the elbow bend. The analysis is ready for 1-2 business days.

- Is it possible to prevent prostate cancer with a PSA test?

The PSA test really allows you to diagnose pathological changes in the prostate gland, which in the future may lead to the formation of carcinoma. To do this, doctors recommend that all men after 45 undergo a laboratory examination every 6 months.

- In what cases is a biopsy necessary after a PSA test?

Without fail, a prostate biopsy is prescribed for patients with an antigen level of 10.0 ng / ml, as well as when seals are detected during a digital examination.

- How often should a PSA test be done?

A general blood test for cancer must be taken every 3 months. After radical treatment - after 8-12 weeks. (Further frequency of examinations depends on the results of the primary test)

- How to lower the PSA level in the blood?

First of all, it is necessary to find and eliminate the cause of the increase in antigen. Depending on the nature of the pathology, the doctor selects the optimal treatment regimen on an individual basis.

Prostate cancer that is detected at an early stage is 100% curable! That is why men who are at risk (over 45 years old, burdened with poor heredity and progressive diseases of the genitourinary system) should regularly measure their PSA levels.

Permissible PSA level for prostatitis

What is PSA? Prostate-specific antigen (PSA) is a special protein that is formed in the male body exclusively by the tissues of the prostate gland, which performs the function of dissolving sperm at the time of ejaculation. The accumulation of PSA in prostatitis in the blood of a male representative directly reflects his age and prostate volume. That is, the larger the prostate gland, the higher the PSA grade. Therefore, it is very important for any man to periodically undergo an examination to determine its amount in the body.

The reasons for the increase in PSA

An increased PSA density usually indicates a dangerous disease of the prostate gland. The reasons for the presented pathology:

  • malignant neoplasm, that is, cancer;
  • BPH;
  • the process of inflammation that develops in the prostate;
  • heart attack or coronary artery disease.

An elevated PSA index is not always caused by prostate disease. In certain situations, this symptom is not a disease. An increase in PSA is observed in such cases:

  • a course of prostate massage;
  • ejaculation;
  • carrying out the procedure for ultrasound diagnostics of male organs;
  • surgical intervention.

In such situations, PSA can rise. Therefore, before going through this study, you should consider such points. After all, the level of PSA in the blood will be atypical.

Indications for PSA testing

A specialist prescribes a blood test for the amount of prostate-specific antigen in such cases:

  • checking the effectiveness of the therapy for cancer;
  • to exclude a malignant tumor, an analysis is made for prostate cancer;
  • as a result of radical therapy of a patient diagnosed with prostate cancer;
  • for the prevention of men 40 years of age and above.

The analysis of the material on the PSA gives a 100% error-free result. Therefore, it is possible to identify the inflammatory process of the prostate and more serious diseases rather quickly, in the early stages of development.

The norm of the concentration of PSA in the body of a man

How to decipher the normal state of protein in a man's blood? The following PSA indicators are considered the norm, depending on age:

  • in young men from 20 to 25 years old, the result should be no more than 2.5 ng / ml;
  • age 25-45 requires PSA 3 ng / ml;
  • in men from 45 to 65 years old - no more than 3.5 ng / ml;
  • older age - the result should not go beyond the PSA range of 4 ng / ml.

That is, if the test result is not higher than 4 ng / ml, this is a normal result, in which a malignant neoplasm is excluded.

BPH

Adenoma is an age-related disease in which the prostate gland enlarges. As a result, it ceases to perform its functions qualitatively, which leads to the development of inflammation or infectious diseases of the genitourinary system. Adenoma of the prostate is not considered a fatal disease, but, nevertheless, significantly impairs the quality of normal life.
In order to detect the disease, you should be tested for the level of PSA in the blood. Before the study, doctors do not recommend eating food for 8 hours, and also refraining from intimacy for 2 weeks.
A PSA of 20 to 40 ng / ml indicates that a man is developing this disease. When this indicator is exceeded, the patient is likely to develop a malignant formation.
PSA levels in prostate adenoma need to be monitored periodically. They should not increase by more than 0.75 ng / ml per year. A more dynamic increase indicates the development of prostate cancer.
What does this indicator mean? The PSA level in prostate adenoma helps the specialist to prescribe the most effective and safe treatment for each individual case.

Prostatitis

Prostatitis is a disease in which inflammation occurs in the prostate gland. This disease affects the PSA level, even if there are no visible changes in the man's body.
Starting effective treatment, the indicator of prostate-specific antigen gradually returns to normal - after about 4 weeks. What does a high PSA reading in prostatitis after therapy indicate? An increased rate can only indicate the development of prostate cancer. Therefore, after undergoing treatment for prostatitis, it is required to pass this PSA general blood test again in a month. Chronic prostatitis requires an indicator check every three months.

Prostate cancer

A significant increase in PSA levels indicates that the man has a malignant tumor of the prostate. If the mark reaches more than 8-10 ng / ml, an active inflammatory process occurs. The prostate gland requires additional research.
There are cases when the PSA values ​​in the blood in prostate cancer are too high - 80-100 ng / ml. With this value, prostate cancer is accurately determined, despite the fact that a man may feel quite well. If an increase in prostate-specific antigen is observed more than 100 ng / ml, an effective, potent therapy is urgently required.

Reducing the level of prostate-specific antigen at home

How to reduce this indicator with folk remedies? You can lower your PSA level on your own, without the use of medications. To do this, you should eat food that helps to relieve the inflammatory process in the prostate gland, namely:

  1. Lean poultry helps to inhibit the process of enlarging the prostate.
  2. Fatty fish. Preference should be given to such species as tuna, salmon, herring.
  3. Dark berries and grapes. They prevent the oxidation of certain tissues, organs and glands, including the prostate.
  4. Eating tomatoes. This vegetable performs the protective function of the tissues of organs and glands, thanks to its constituents. Watermelons and apricots have the same property.
  5. Freshly squeezed pomegranate juice. It prevents the accumulation of cancer cells in the prostate gland, thereby reducing the amount of protein in the blood. It is required to consume at least 1 glass of pomegranate juice daily.

Men will also benefit from using a variety of dietary supplements. Their advantage is the complete absence of contraindications and side effects.

Medication reduction

What should a man do with high PSA? If a man has a large amount of this protein as a result of an analysis of PSA levels in his blood, additional research is required to identify cancers and inflammatory processes.
In order to lower protein levels, the following medications should be taken:

  1. Aspirin and other non-steroidal anti-inflammatory drugs. Medicines of this group thin the blood, while decreasing the PSA level. The maximum effect is observed in nonsmoking men, even with prostate cancer. In addition to their blood thinning function, non-steroidal anti-inflammatory drugs help to improve the functioning of the cardiovascular system.
  2. Cholesterol-lowering drugs. Taking them regularly for a long period helps to exclude an increase in PSA.
  3. Medicines to improve the functioning of the cardiovascular system.

That is, it is not necessary to use drugs to lower PSA. It is enough just to normalize the work of the cardiovascular system.
You can also reduce PSA, which was found together with diseases of the prostate gland, in the following ways:

  • cryotherapy;
  • thermotherapy;
  • microwave treatment;
  • laser coagulation;
  • urethral resection.

These methods of affecting the prostate gland contribute to the removal of a malignant tumor and the elimination of the inflammatory process through the urethra.

Prevention of PSA increase

In order to maintain the PSA level in the normal range, that is, not to exceed the 4 ng / ml mark, preventive measures are required. They should be aimed at excluding possible inflammation and enlargement of the prostate gland. To do this, you should adhere to the following rules:

  1. Timely conduct effective therapy in the event of infectious and viral diseases.
  2. Elimination of intestinal disorders. Effectively affect the elimination of anal fissures, hemorrhoids and other diseases.
  3. Intimacy should be only with a constant partner. Promiscuous intercourse increases the risk of sexually transmitted diseases, which lead to inflammation of the prostate.
  4. Observe the rules of personal hygiene, which will eliminate the risk of developing infectious diseases.
  5. Give up addictions. Excessive drinking and smoking negatively affects men's health.
  6. Physical exercises. Poor physical activity leads to congestion of the small pelvis.
  7. Proper nutrition. Eating healthy foods helps to boost immunity.

You should also not forget about adherence to the daily regimen, which will ensure a high-quality distribution of activity during the day and good rest.

Mandatory for men is PSA analysis for prostatitis. With its help, the prostate specific antigen, which is produced by the prostate gland, is determined. The amount of this substance in the male body can tell a lot about the current state of human health. If prostatitis is suspected, this analysis is one of the first, since it can be used to identify or exclude the development of a prostate adenoma or a malignant tumor in an inflamed organ.

The study helps to identify the development of oncology or adenoma even before the onset of symptoms of the disease

PSA is a prostate specific antigen. This is the name of a special protein that is produced in the body of a man exclusively by the prostate. The prostate-specific antigen performs the function of dissolving the family fluid during ejaculation.

The accumulation of this antigen during inflammation in the prostate gland is a reflection of the volume of the prostate and the age of the man. The larger the internal organ, the higher the PSA level.

Indications for research

PSA for prostatitis is a mandatory test. A referral for its delivery is prescribed by a doctor who observes a man with complaints of symptoms of inflammation in the prostate gland.

PSA analysis is indicated for men in the following cases:

  • monitoring of the development of a malignant tumor in the prostate gland is required;
  • there is a suspicion of the development of cancer in the prostate gland;
  • prevention of diseases of the genitourinary system is carried out;
  • an assessment of the dynamics of a man's recovery after undergoing anticancer therapy is required.

In the latter case, the analysis is carried out every 3 months. This is a mandatory measure to make sure there is no recurrence of the disease.

How to prepare for the study


Drinking alcoholic beverages before the procedure is strictly prohibited

A blood test, which allows you to check PSA (total) for prostatitis, is done after preparation for the diagnostic procedure.

Before sending the patient to the test, the specialist should tell him about the ways to prepare for the diagnosis. The reliability of the result obtained after the study depends on the quality and correctness of its implementation.

A patient who is to be analyzed for the level of PSA in the body with prostatitis must adhere to the following rules regarding preparation for diagnosis:

  1. You must refrain from intercourse for 7 days before the diagnosis.
  2. It is necessary to wait a period of 2 weeks after the rectal palpation of the patient.
  3. 8 hours before the analysis, you should stop eating and sugary drinks. Alcohol is also banned.

After the analysis for PSA in prostatitis, it will be clear whether the content of this protein is increased or is within the normal range.

An increase in prostate specific protein does not always indicate pathology. This result is obtained if manipulations were carried out that involve the bladder. Also, this reaction is explained by the presence of an inflammatory process in the prostate.

The urologist should explain to his patient in detail the importance of the PSA analysis and the interpretation of its result. A man who requires such a diagnostic option will understand that an increase in the level of protein does not guarantee the development of a malignant process in the body. Less dangerous factors can also lead to this change. Most often, such a PSA indicator is detected in chronic prostatitis.

Analysis

Biological material for analysis from a man who requires PSA diagnostics in acute prostatitis is taken at the clinic. The study of the sample takes no more than a day.

To pass the analysis, the patient must receive a referral from the urologist. After that, preparation is made. To study the PSA level, a blood test is required, which is taken from a vein.

Rate and deviations


The attending physician - urologist will always tell you what the studies have shown

PSA for prostatitis is not the least important. To decipher the results of the analysis, it is required to compare the indicators of the antigen rate in the man's body and the current level.

In the process of conducting a general blood test and other types of laboratory diagnostics, a specialist finds out the level of this substance. Its rate is presented in the table.

Based on the data in the table, we can conclude that any PSA level values ​​that exceed 4 ng / ml are abnormal. With such analysis results, doctors can talk about the development of malignant processes in the prostate gland in a man. This theory can be verified by instrumental diagnostic methods.

An increased level of prostate specific antigen is not always evidence of malignant processes in the body. This result can be obtained in a man who has prostatitis. And this disease does not belong to the group of cancers.

If the diagnosis showed an antigen content in the range of 4-10 ng / ml, then a man may have the following diseases:

  1. Chronic or acute prostatitis;
  2. Benign prostatic hyperplasia;
  3. Malignant tumor in the prostate gland.

A high level of antigen is diagnosed with prostate adenoma. If you do not start taking measures to solve this problem, then the pathology will eventually lead to the development of a malignant process.

If the PSA concentration increases and reaches more than 10 ng / ml, then the risk of developing a cancerous tumor in the genitourinary system is significantly increased. This probability increases by 67%.

The antigen level depends on the form of inflammation in the prostate gland. In most cases, it is used during differential diagnostics, which allows you to distinguish prostatitis from other diseases of the genitourinary organs that have similar symptoms.


After undergoing penile surgery, PSA may be increased

There are a number of factors that can cause your PSA level to be elevated. This diagnostic result indicates the presence of serious diseases that negatively affect the functioning of the prostate gland.

The following factors lead to an increase in prostate specific antigen:

  • Malignant neoplasm in the prostate;
  • Prostate adenoma;
  • Inflammatory process in the genitourinary system, which affects the tissues of the prostate;
  • Ischemic disease or prostate infarction.

An increase in PSA is observed not only with prostatitis, but also under other circumstances. Often, urologists do not consider it as the main symptom of the disease. An increase in the level of prostate specific antigen may well be due to the following reasons:

  • Recent therapeutic prostate massage;
  • Ejaculation that has occurred;
  • Ultrasound diagnostics of the internal organs of the small pelvis;
  • Biopsy of prostate tissue;
  • Surgical intervention on the organs of the male reproductive system.

These points must be taken into account by the urologist at the time of the appointment of the PSA diagnosis.

How often to get tested

Experts recommend that men who have reached the age of 45 be tested for the level of prostate specific antigen every year. They are at risk and, if preventive measures are not followed, they can develop genitourinary pathologies, including prostatitis.

Every patient with chronic and acute prostatitis should have a PSA test. This is a mandatory requirement for diagnosis for this disease.

If a man has immediate family members who have been diagnosed with prostate cancer, then he is at risk. For this reason, he should have his antigen level checked annually from the age of 30. This measure will allow timely identification of the development of benign or malignant processes in the prostate gland.

Contraindications to diagnostics


At high temperatures, the analysis should be postponed

PSA analysis may be contraindicated in a man, since this diagnosis has a number of limitations.

Doctors prohibit donating blood for antigen analysis in the following cases:

  1. The man suffered from severe food poisoning and still has complaints of its symptoms;
  2. An increase in temperature is observed, which differs from the norm by 0.5 degrees or more;
  3. The patient suffers from an infectious disease that is in the acute stage.

The acute and chronic form of prostatitis are not among the limitations for the analysis. They are one of the important indications for this diagnosis.

Neglect of regular PSA diagnostics in case of prostate inflammation can threaten the patient with significant complications and the development of oncology.

PSA (prostate specific antigen) Is a special protein chemical structure designed to liquefy the ejaculate. Normally, this protein is produced by the cells of the prostate gland and is part of its juice, entering the bloodstream in minimal quantities. An increase in PSA does not bode well for the patient, since it occurs in about 60% of clinical cases. Somewhat less often, we are talking about other diseases of the prostate.

An increase in PSA is not an independent diagnosis, but only a sign, a symptom.

An increase in PSA may indicate a malignant tumor.

Pathological causes

An increase in PSA develops most often with a cancerous lesion of the organ. But this is not necessary, and an increase in PSA is not a clear sign for oncology. Sometimes there are other lesions of the prostate. Most often, the reason lies in the following diseases:

Prostate cancer

Malignant lesion of the prostate gland is in third place in the structure of all malignant pathologies in men in general. Only lung and stomach cancer is somewhat more common. In the course of the pathogenic process, the proliferation of tissues of the glandular organ and their infiltrative, diffuse growth are observed. The causes of the disease are manifold. Most often, it is about an increase in the level (while androgens by themselves are not considered carcinogens). Metabolic changes in the male body are not always the root cause of the disease. Sometimes we have to talk about the impact of an infectious factor, radiation (ionizing radiation), etc.

Prostate specific antigen is actively produced by atypical cells (cancerous cytological structures), which is why it is called a marker of prostate cancer.

PSA - a marker of prostate cancer

Prostatitis

It is defined as a degenerative-dystrophic disease of the prostate gland with a gradual increase in dysplasia and atrophy of the muscular-glandular organ. In the overwhelming majority of cases, it is non-infectious. This disease is characterized by intense pain in the projection of the prostate, discomfort in the rectal opening, impaired potency (there is a weak, insufficient erection, lack of ejaculation), problems with emptying the bladder (a representative of the stronger sex literally becomes a hostage to the toilet room). In the course of the disease process, patients also note fertility disorders: there is an inability to conceive a child.

In the initial period of prostatitis in laboratory parameters, there is a decrease in the concentration of prostatic specific antigen, its high values ​​appear only in the advanced stages of the disease. This requires more than one year.

Benign Prostatic Hyperplasia (BPH)

Provoked by excess androgen production. The result is the proliferation of the glandular tissue of the organ: massive or focal. As the number of synthesizing cells increases, so does PSA synthesis. The result is an increase in the concentration of the substance. A similar cause is somewhat less common than cancer, but it still takes place.

With prostate adenoma, an increase in PSA is observed

Physiological causes

An increase in the protein under consideration does not always indicate in favor of neoplastic processes. In medical practice, there is such a term as a false increase in prostate specific antigen. A similar condition occurs when:

  • ejaculation (immediately after);
  • massage of the prostate gland (PSA begins to be produced more actively);
  • biopsy of the prostate;
  • transurethral interventions on the glandular organ.

It is necessary to carefully interview the patient and give recommendations for preparing for the study.

How to properly prepare for the study?

  • refuse sexual contact and masturbation;
  • refuse to visit baths, saunas, hot baths.

Reference indicators

Normally, the PSA concentration varies between 2-4 units. Anything more is already a conditional pathology. With age, the production of specific prostatic antigen increases, therefore the reference value also increases: on average, for each year of life, the rate increases by 0.1-0.2 units. So, by the age of 80, the norm grows from 4 units to 7.3 units. However, we are talking about the upper limit of the norm.

Normal PSA values ​​also depend on the patient's age.

Additional diagnostics

An increase in PSA alone is not informative enough for making, and even more so for verifying, a diagnosis. The identification of an increased rate suggests one of the three diseases indicated above. Thus, the result of an objective study makes it possible to determine in which direction to move on in diagnostics. Anamnesis collection and additional studies are shown. As they say, by eye, it is impossible to distinguish cancer from hyperplasia and from prostatitis.

It is important to consider the following factors:

  • Has there been sexual contact in the recent past?
  • Did you have intense physical activity?
  • Is there a verified prostatitis or prostate adenoma?

Having received answers to these questions, the specialist will be able to quickly navigate the situation. The following studies are shown in the following:

  • ... It makes it possible to diagnose tumors and neoplastic processes, as well as prostatitis, by typical echo signs.
  • ... Allows you to identify prostatitis even in the early stages.
  • ... It also makes it possible to determine the inflammatory lesion of the prostate.

If PSA levels are higher than normal, further testing is done.

If a tumor is found, a biopsy is performed to assess the histological and morphological structure of the musculo-glandular organ. This is a mandatory procedure even with prostatic hyperplasia.

Treatment

Therapy is aimed not so much at lowering PSA as at eliminating the root cause, which is logical: the cause will go away, and the effect will also disappear. The therapy of the underlying disease is performed, including medication with the use of:

  • antispasmodics;
