Should I have a PSA test?
It is a real decision, not a formality — and reasonable men reach opposite conclusions.
There is no national screening programme precisely because the balance is close. What shifts it towards testing: a family history, and Black African or Caribbean heritage.
Does a raised PSA mean I have cancer?
No — most men with a raised PSA do not.
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 bone pain, weight loss or blood in the urine.
What does overdiagnosis actually mean?
Finding a cancer that would never have harmed you. Some prostate cancers grow so slowly they would never cause 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.
I am Black. Does that change things?
Yes, substantially — and it is not communicated nearly well enough.
Black African and Caribbean men have roughly double the risk and tend to develop it younger. The conversation should start around 45, and you may need to ask for it rather than be offered it.
I take finasteride. Does that affect my PSA?
Yes, considerably — it roughly halves it.
The result must be doubled to be interpreted, so tell any doctor checking it that you take it, whether it is for hair loss or for your prostate. This is missed regularly and produces falsely reassuring results.
I am up three times a night. Is that cancer?
Almost certainly not. That is usually benign prostate enlargement, which is common and treatable — and early prostate cancer typically causes no urinary symptoms at all.
It is also worth asking about sleep apnoea, a frequently missed cause of waking at night that has nothing to do with the prostate.
Can you examine my prostate?
No — that needs an in-person examination. We can arrange the blood test, interpret it properly, and write to your GP.
Does a vasectomy or cycling cause prostate cancer?
No. Neither is a risk factor.
Cycling does temporarily raise PSA though, which is why it is worth avoiding for 48 hours before a test.
