I feel a bit awkward here among the blokes, but you might like to hear the wife's point of view. During a visit to the UK a few years ago I pushed my husband to go to the doctor over leg pains (still no idea what caused them). Various tests were prescribed and I asked the GP to request an HbA1C and a PSA as well. Only these two came back with worrying results and within a few weeks he had to choose between surgery and radiotherapy for prostate cancer. The hormone implants were done by the local nurse in France, and we stayed in the UK for the radiotherapy at the Royal Marsden Hospital, where Philip was part of a trial as his cancer showed a definite "focus" rather than being throughout the gland. He will be observed for life (how else will they know how many extra years the treatment has given him?) and has phone consultations every 6 months, with PSA tests done in France and sent across to the RMH.
Looking back, the cancer was not that new, but some of the symptoms could apply to either prostate cancer or the Type 2 Diabetes diagnosed as a result of the same blood test. He had no strong symptoms then, and so I can't really say he feels better for the treatment, only that I'm extremely glad that we found out about the prostate cancer when we did. My father had it, as did my paternal grandfather, in Dad's case it spread to the bowel, and in Grandpa's to the bowel and bones before it was diagnosed. It was cited as cause of death for both of them.
PSA testing is not perfect. High results can be down to multiple reasons, as can such symptoms as there are. Many GPs say it isn't worth screening all men, but that's no excuse for ignoring the possibility that the cancer is there. It is very common indeed. Yes, the first examination is very intimate (but no worse than your wife's cervical smears) and then there is a biopsy before diagnosis is clear, and several scans. Please discuss it with your GP next time you see them, and make an excuse to do so if you don't regularly see a GP. Phil found cataracts more distressing than prostate cancer. RMH are investigating genetics in relation to prostate cancer and both my sons are on their contact list as both sides of their family have had it: both are Type 1 diabetics so have blood tests regularly anyway.
Philip has supported me through all the ups and downs of life, but the most important thing he has ever done for me was to have that first PSA test and follow through with his treatment. He is the biggest coward in the world where medical matters are concerned, so if he can do it, any man can. Please talk to your doctors about it. It matters - as you do.
