The problem, gentelemen, as has been said on PPRUNE before, is that the incidence of prostate cancer is very high - 'almost' everyone has it by the age of 80, but in some it is so slow growing that you die of old age decades before it is a problem whilst in others it is rapidly invasive.
Perhaps the best advice is to get tested if you have any symptoms, treat any PSA abnormality with care, and above all try to ensure you are referred to a good urologist who uses all options and does not just reach for the knife
