Not sure about prostate cancer but I had a right lung upper lobectomy 18 months ago due to squamous cell carcenoma. I was given 3 months to live and only 35% chance of surviving sugery!. Lung came out easy with the tumor, had no narcotic meds after and got Class 1 medical back after 6 months. Now FAA want pathology reports etc 18 months later!!!!!, anyway surgeon says all is well. Moral is, if you want it bad enough, go for it. I am flying corporate in middle east and having a blast...Cancer can be the end, but also the beginning...never give up. Fight and Fight, then when you have no fight left.....fight again...you can win.
