OK Bob,
Going forward, get your Dad sorted for an MP-MRI scan, followed up with a transperineal biopsy, if his clinicians think it’s appropriate.
Don’t waste everybody’s time with another, now largely discredited, TRUS biopsy, as there are guys here who have had three inconclusive ones, only to have a fourth transperineal biopsy which confirmed their prostate cancer.
Bear in mind that 60% of men in their sixties have some cancer in their prostate, and most will die with it, blissfully oblivious, rather than of it.
If your old man is confirmed with PCa, bear in mind that is an additional risk factor for yourself!
When you reach fifty, insist on regular PSA tests, and don’t let your GP palm you off with some leaflet or flannel about ‘You have no symptoms, why do you need a test?
Best of luck to Papa.
Cheers, John.
