Hi, I am currently recovering from surgery after a radical prostatectomy three weeks ago.Like you, I had absolutely no symptoms and was stunned when informed that I had cancer..
I'm a little younger than you (62) so it was fairly obvious to me, that it was critical that I get rid of the offending organ. My gleeson score was 7, but the interesting point to me was that the post Op pathology showed a lot more cancer in the prostate than showed up in the pre-op biopsy, so that had I opted for radiotherapy or brachytherapy, it would have been the wrong decision. The good news is that there was no sign of spread to the surrounding tissue, so we are waiting until the follow-up tests to confirm that I am now clear.
Like you, I am very active, still working and with a lovely wife, who for some reason loves me dearly, still very sexually active, so you can understand my reluctance to make the decision for a "radical". I very nearly took no action at all and was prepared to just let the cards fall where they may.
Obviously, we will have some adjustments to make as we go forward, but the view ahead is looking better all the time. I wish you well in whichever decision you make.
Cheers,
Ron (NSW Australia)
