Should I have a PSA test?
It is a decision worth twenty minutes rather than a yes or no, and reasonable men reach opposite conclusions on the same evidence.
There is no national screening programme precisely because the balance is close. What shifts it: a family history of prostate cancer, and Black African or Caribbean heritage, both of which raise risk substantially.
Does a raised PSA mean cancer?
No — and most men with a raised PSA do not have it.
Benign enlargement, infection, prostatitis, recent ejaculation and cycling all raise it. A raised result means further assessment, not a diagnosis.
Does a normal PSA mean I am clear?
No. A proportion of significant prostate cancers occur with entirely normal PSA levels.
Symptoms still matter — a normal result is not a reason to ignore a change in urinary pattern, bone pain or weight loss.
What should I avoid before the test?
Ejaculation for 48 hours, and vigorous exercise or cycling for 48 hours — both genuinely raise PSA and produce results that need repeating.
And postpone for at least six weeks after a urinary infection or any prostate procedure.
I take finasteride. Does that matter?
Yes, considerably — and it is missed regularly. Finasteride and dutasteride roughly halve PSA, whether taken for hair loss or for prostate enlargement.
The result must be doubled to be interpreted, so tell any doctor checking it that you take it.
What happens if my PSA is raised?
Not an immediate biopsy. Current UK practice is multiparametric MRI first, which frequently avoids biopsy altogether and targets it better where one is needed.
That is a meaningful improvement on the older pathway, and worth knowing when weighing whether to test.
What does "overdiagnosis" actually mean here?
Finding a cancer that would never have caused you harm. Some prostate cancers grow so slowly that they would never produce symptoms or shorten life.
The difficulty is that once found, they are hard to leave alone — and treatment carries real risks of incontinence and erectile dysfunction. That is the central argument against routine screening, and it deserves stating plainly.
Can you examine my prostate?
No — that requires an in-person examination, which we cannot do. We can arrange the blood test, interpret it, and refer.
Are prostate supplements worth taking?
Saw palmetto and similar products have not shown convincing benefit in good trials for either symptoms or prevention.
Some may also affect PSA readings, which is an unhelpful side effect for a product bought by men worried about their prostate.
I am getting up several times a night. Is that cancer?
Usually benign prostate enlargement, which is common and treatable. Prostate cancer typically causes no urinary symptoms at all until it is advanced.
Worth mentioning: sleep apnoea is a frequently missed cause of getting up at night, and it is not a prostate problem at all.
