I am 63 and had stage 1 cancer. My options were to do nothing, do what I call the Roto-Rooter option (partial removal) and a full removal. The first 2 options would mean I would probably still have to deal with the cancer later and I would probably need to continue doing the self-catheter due to my bladder retention. Since I lost both of my parents to cancer, I went with the robotic assisted radical Prostatectomy at the end of October. The surgery and surgical recovery went very well - even with the Foley catheter in for 3 weeks. The incontinence that I am dealing with now is hard, but I will get through this. There is no question I make the same choice.
Good luck with your journey.
