PSA and prostate health: what it is and when to talk to your doctor

PSA is one of the most searched men's health topics — and one of the most misunderstood. Understanding what it measures (and what it does not) helps you have the right conversation with your doctor.

What PSA is

PSA (prostate-specific antigen) is a protein made by the prostate that can be measured in a blood test. A higher value can reflect several situations — and not all of them are concerning.

It helps to know this from the start: a raised PSA does not, on its own, mean cancer. Benign prostate enlargement (very common with age), an infection or even recent physical activity can raise it temporarily.

Why it is a decision to make with your doctor

Unlike some other screenings, PSA is not recommended indiscriminately to every man. The main international recommendations describe it as a shared decision.

In that conversation, the doctor weighs the benefits (earlier detection in some cases) against the downsides (false positives, further tests, and the detection of slow-growing tumours that would never cause harm). So the right question is not only "should I do a PSA?", but "does it make sense for me, given my age and history?".

When it usually comes up

The PSA discussion typically starts from age 50, or earlier when there are factors such as a family history of prostate cancer. Above a certain age the benefit tends to fall, and the decision becomes individual again, case by case.

None of this replaces your doctor's assessment: these are general references, to help you prepare the conversation with information.

What you can do today

A few simple steps leave you better prepared — without alarm and without deciding alone:

  • Know your family history of prostate conditions and take it to your appointment.
  • Avoid ordering or buying the test on impulse: a single value, with no context and no one to interpret it, tends to create more anxiety than information.
  • Take the free check-up: in a few minutes you learn whether PSA — and which other exams — make sense for you, and take a clear plan to your doctor.
