The article is for educational purposes and does not replace a urological consultation or discussion of the results with a doctor. It is not intended for independent interpretation of your own PSA result. Urinary retention, blood in urine or semen, fever with lower back pain, severe lower abdominal pain, bone pain or rapidly increasing urinary symptoms require urgent medical evaluation.

The most important information at a glance

• PSA is a protein produced by prostate cells. It is organ specific, not tumor specific.
• The test involves taking a venous blood sample. It does not require fasting, but requires a few days of preparation.
• PSA may be elevated in benign prostatic hyperplasia, prostatitis, urinary tract infections, after ejaculation, cycling, catheterization and biopsy.
• There is no single cut-off value dividing results into good and bad. The historical value of 4 ng/ml is a simplification, not the limit of diagnosis.
• The conversation about the examination usually begins around the age of 50, and earlier in the case of family history.
• The frequency of repetition depends primarily on the baseline PSA value and individual risk, rather than a rigid regimen for everyone.
• A single increased result is not the basis for a decision. The rule is to repeat the determination after an appropriate period of time.
• Drugs from the group of 5-alpha-reductase inhibitors, used in prostate diseases and alopecia, reduce PSA by approximately half. You must inform your doctor about them.
• A normal PSA does not rule out prostate cancer, and an elevated PSA is not a diagnosis.
• PSA is never the only parameter. They are assessed together with digital rectal examination, the dynamics of the result, prostate volume, age and, if necessary, magnetic resonance imaging.

What is PSA?

PSA is an abbreviation for prostate-specific antigen. It is a protein enzyme produced by prostate epithelial cells. Its natural role is to liquefy semen after ejaculation, which allows sperm to move.

Most of the PSA ends up in the semen, but a small portion passes into the blood and is what we measure in the laboratory test. It is crucial to understand what the word "specific" in the name means. PSA is specific for prostate as an organand not for prostate cancer. In other words: the result tells us that something is happening in the prostate gland, but it does not say what exactly.

The concentration of PSA in the blood always increases when the structure of the prostate is damaged in any way or when the gland is larger. Enlargement of the prostate in benign hyperplasia, inflammation, infection, mechanical trauma, and cancer growth - all these situations increase the penetration of PSA into the blood. Therefore, an increase in value alone does not indicate the cause.

PSA exists in the blood in two forms: protein-bound and free. This difference is diagnostic for some results and we will return to it later in the article.

What does the examination look like and how to prepare for it?

The test itself is simple: it involves taking a sample of venous blood, usually from a vein in the bend of the elbow. It does not take longer than regular laboratory tests and does not require fasting.

Preparation is more difficult because many everyday situations influence the result. Neglecting these rules is the most common cause of unnecessary anxiety and repeating the examination.

The last line deserves to be underlined. A man who has been taking a 5-alpha-reductase inhibitor for a long time and has a PSA level of 2 ng/ml should be assessed as having a PSA level of approximately 4 ng/ml. Without this information, the doctor may consider the result to be correct, although in fact it would require further diagnostics. This also applies to men taking these medications solely for hair loss.

It is also worth performing subsequent tests in the same laboratory. The methods used by different laboratories may produce slightly different results, and when comparing values ​​over time, this difference is important.

Why test PSA at all?

Prostate cancer is one of the most common cancers in men and may not cause any symptoms for a long time. This is important because it leads to two wrong conclusions. The first: "there's nothing wrong with me, so I don't need an examination." Second: "I have trouble urinating, so it must be cancer." Both are inaccurate. Lower urinary tract symptoms most often result from benign prostatic hyperplasia, and early cancer usually does not cause them.

PSA allows you to spot situations that require a closer look at the prostate before symptoms appear. However, it has limitations that need to be talked about honestly. It can detect cancers that would not pose a life-long risk to the patient, leading to unnecessary anxiety, biopsies and treatments. It may also be normal despite the presence of cancer.

That's why modern guidelines do not say "every man over 50 is obliged to do a PSA", but "every man should have the opportunity to consciously talk about this test." The decision should take into account age, health condition, life expectancy, family burden and how the patient would cope with the consequences of further diagnostics. This approach is called shared decision-making and is the standard today.

At what age to start and how often to repeat?

The starting point depends on your individual risk. The framework below follows the approach taken in European guidelines, but in each case it is decided by the doctor after talking to the patient.

The repetition rate is not the same for everyone. In a risk-adjusted approach, the baseline PSA value is the basis: the lower it is, the less often the test needs to be repeated. A man with a very low PSA at age 50 has little risk and does not need annual monitoring. A man with a higher value, although still within the limits considered normal, requires more frequent observation.

Therefore, instead of asking "how many years to do PSA", it is worth asking the doctor: "given my result and my risk, when should I repeat the test?" This question leads to a specific answer, not a general pattern.

What does the result mean? Why there is no single standard

The value of 4 ng/ml functions in patients' minds as the boundary between health and disease. This is a simplification that has long ceased to be sufficient in clinical practice.

There are several reasons. The prostate enlarges with age, so the same value means something different in a seventy-year-old man than in a fifty-year-old man. Prostate cancer is sometimes diagnosed in men with PSA below 4 ng/ml. On the other hand, many men with results above this limit do not have cancer, just an enlarged or inflamed prostate.

Therefore, the doctor does not evaluate the number itself, but several parameters at once:

• The absolute value of PSA related to the patient's age.
• Dynamics over time. Systematic growth over subsequent years may be more important than a single increased result. The doubling time is also important.
• PSA Density. PSA value related to the prostate volume measured by ultrasound. A high PSA in a very large prostate means something different than in a small prostate.
• Percentage of free PSA. In case of intermediate results, a low percentage of the free fraction indicates cancer, a higher percentage indicates benign hyperplasia.
• Rectal examination. Abnormal consistency or lump changes management regardless of PSA value.
• Symptoms and history. Family history, previous results, comorbidities, medications taken.

This creates a situation that can be confusing for patients: two men with the same PSA result may receive completely different recommendations. This is not an inconsistency, but a consequence of the PSA being interpreted in context.

What raises PSA other than cancer?

This question is asked by every man who has seen a result that exceeds the reference range. The list of non-cancer causes is long:

• benign prostate hyperplasia, i.e. its enlargement with age - the most common cause,
• prostatitis, acute or chronic,
• urinary tract infection,
• ejaculation within a day or two before the examination,
• cycling, horse riding, long-term pressure of the perineum,
• bladder catheterization,
• cystoscopy, prostate biopsy and other procedures,
• urinary retention,
• digital rectal examination immediately before blood collection,
• intense physical exercise on the day before the examination.

This is why there is a rule worth remembering: a single increased result is not the basis for any decision. The standard procedure is to repeat the test after an appropriate period of time, maintaining the preparation rules and after excluding infection. In a significant proportion of men, the second result turns out to be correct.

What is the PSA level for prostate cancer?

This question is asked very often and requires an answer that may be disappointing: there is no specific value for prostate cancer. There is no number at which the diagnosis can be made or at which it can be excluded.

All we can say is that as the PSA value increases, the probability of detecting cancer increases. But this is a statistical relationship for groups of patients, not a prediction for a specific man. In practice, both situations occur: a very high PSA with a large, benignly enlarged prostate accompanied by inflammation, and a clinically significant cancer with a PSA within the range considered normal.

It is especially worth remembering this second possibility. Some cancers, especially those with a higher degree of malignancy, produce relatively little PSA. This is one of the reasons why you should not give up a digital rectal examination just because the laboratory result is good.

The diagnosis of prostate cancer is made solely on the basis of microscopic examination of the biopsy material. PSA and MRI are used to decide whether and where to perform a biopsy.

What next if PSA is elevated?

An elevated result does not mean an immediate biopsy. The procedure is gradual.

The order matters. Performing an MRI before the biopsy allows some men to avoid the procedure, and for others, it allows to precisely indicate the place where the material was taken. We write about how to read the MRI result and the subsequent biopsy result in a separate article: PI-RADS and Gleason score.

When to see a urologist?

Consultation is indicated when:

• the PSA result exceeds the laboratory reference range,
• PSA systematically increases in subsequent tests, even if it is within the norm,
• the patient is over 50 years old and has never talked to a doctor about prostate examination,
• prostate cancer occurred in the father or brother,
• there is a family history of cancer associated with the BRCA mutation,
• symptoms appear: weak urine stream, frequent getting up at night, urgency, feeling of incomplete bladder emptying,
• there is blood in urine or semen,
• the patient is taking finasteride or dutasteride and does not know how to interpret his PSA,
• there is bone pain, especially in the spine and pelvis, which is persistent and intensifying,
• the patient simply does not understand his own result and wants to discuss it.

The last point is more important than it seems. Many men postpone the visit because they are afraid of hearing the diagnosis. Meanwhile, in most cases, the conversation ends with an explanation that the elevated PSA is due to an enlarged prostate or inflammation. Postponing an appointment doesn't change the outcome - it just changes the amount of time the patient lives in uncertainty.

The most common myths about PSA

• "PSA is a test for prostate cancer." No. This test is specific for the prostate as an organ, not for cancer.
• "Above 4 is cancer, anything below is fine." No. There is no single limit value. Cancer is sometimes diagnosed at lower levels, and high PSA often has a benign cause.
• "If the PSA is normal, I don't need a digital rectal exam." No. Some cancers produce little PSA, so medical examination remains important.
• "Elevated PSA means biopsy." No. First, the determination is repeated, the test conditions are assessed and additional diagnostics are performed.
• "I have no symptoms, so the test is unnecessary." No. Early prostate cancer usually has no symptoms.
• "I'm having trouble urinating, it's definitely cancer." No. These symptoms most often result from benign prostatic hyperplasia.
• "The result from every lab is the same." No. The methods may differ, so subsequent tests should be performed in the same place.
• "The cure for baldness has nothing to do with PSA." No. Finasteride lowers PSA by about half and your doctor needs to know this.

Got your PSA result and don't know what to do with it?

The number itself is not enough. A urological consultation allows you to compare the results with your age, prostate size, symptoms, medications you are taking and previous measurements, and determine whether further tests are needed.

FAQ - PSA after 50

What is PSA?

This is a protein produced by prostate cells, whose task is to liquefy semen. A small part of it penetrates into the blood and its concentration is measured by the test. PSA is specific for prostate but not cancer.

How to prepare for the PSA test?

It is usually recommended to refrain from ejaculation for about two days, avoid cycling, wait after a urinary tract infection and have blood drawn before a rectal examination. There is no need to fast. Please tell your doctor about any medications you are taking.

At what age should I start testing for PSA?

The conversation about the test usually begins around the age of 50. In the case of prostate cancer, the father or brother develops it earlier, around the age of 45, and in BRCA2 mutation carriers, usually from the age of 40.

Repeat the test every few years?

There is no one scheme for everyone. The frequency depends primarily on the baseline PSA value and individual risk - the lower the result, the less often the test needs to be repeated. The specific date is set by the doctor.

What is the PSA standard?

There is no single limit value. The historical figure of 4 ng/ml is an oversimplification. The result is assessed in relation to age, prostate volume, dynamics of changes and medical examination.

Does elevated PSA mean cancer?

No. The most common cause of elevated PSA is benign prostatic hyperplasia. Prostate inflammation, infection, ejaculation, cycling, catheterization and procedures can also increase the result.

Is PSA always high in prostate cancer?

No. Some tumors produce relatively little PSA, so a normal result does not exclude the disease. For this reason, digital rectal examination remains a component of the evaluation.

What to do if the result is elevated?

Do not make decisions based on one marking. The standard is to repeat the examination after an appropriate period of time, after excluding infection and observing the preparation rules, and to undergo a urological consultation.

Do prostate or hair loss medications affect PSA?

Yes. Finasteride and dutasteride lower PSA by approximately half. The doctor must know about them in order to correctly interpret the result. This also applies to the use of these drugs solely for hair loss.

What is Free PSA?

This is the PSA fraction not bound to blood proteins. Its percentage can be helpful for intermediate results: a low percentage of the free fraction suggests cancer, a higher percentage indicates benign hyperplasia. The decision on the marking is made by the doctor.

Is PSA the only prostate test?

No. The assessment also includes digital rectal examination, history, prostate volume on ultrasound, PSA dynamics, and, if necessary, magnetic resonance imaging. The diagnosis of prostate cancer is made only by biopsy.

Who discusses PSA results at WMP?
