Tazz, men with localised prostate cancer (me included!) generally don’t have any symptoms, but that doesn’t mean that it can or should be ignored. If it’s left untreated, it’ll spread, and if it spreads from the prostate to other parts of the body, it’s then advanced prostate cancer which is what does kill people. Active surveillance will generally not be offered for Gleason 3+4 cancer.
Prostate cancer is generally slow-growing, so there’s no rush to have surgery, in the sense that it’s unlikely to make any difference whether your husband has surgery next month or in 3 months’ time, but it would be unwise to delay it for years, because the more the cancer spreads, the higher the chance that surgery won’t get it all. The earlier that surgery is done, the better the odds of a curative treatment.
I know from personal experience that the prospect of major surgery is not a pleasant one. In my own case, the scans I had to investigate my prostate cancer also revealed that I had a localised kidney tumour (again with no symptoms), and on 1st September I had my left kidney removed. Not a pleasant experience, and I’m still recovering from the surgery, but I had no doubts at all that it needed removing, and the earlier it was done the better the chances of it completely eradicating my kidney cancer.
So my suggestion would be to follow your consultant’s advice and get the surgery done.
All the best,
Chris
