And if you are 1 of those 20% then you don't 'wonder' for more than a second about the options. After that decision you (I) will never know which treatment would return the best outcome. I'll never know whether I should have opted for active surveilance or the other treatments, but I'll also never know if I escaped a painful and shortened life. The problem with 'going on with their normal lives' is like me, you take your health for granted and miss the opportunity to catch it early.
I was fit as a butchers dog when my biopsy returned a Gleeson of 4+5. I had to make a quick decision and thankfully Siriraj in Bangkok had the equipment and experience to deal with it. Radiotherapy had some side affects that I could have lived without , but I'm here 18 months later and reasonably healthy. My s3x drive has diminished but I put that down to the female hormone injections...2 more to go and then I'm hopeful I'll be back in action.. There's a slight issue with bladder/bowel control, but certainly not requiring pads, mainly the interrupted sleep from multiple bathroom visits.
Good luck to anyone suffering from this, hope it works out well for you.
