Good on you for doing what you can. There has definitely been advancements. I heard in recent years they've come up with targeted radiation for the prostate which should preclude traditional surgery to remove it. I know one fella years ago now, who went through the surgery and said it was bloody horrible and wouldn't wish it on his worst enemy...well that scared the "crap" outta me. But this new treatment of injecting radiation "capsules or pellets" right into the prostate is far preferable to regular surgery, if I recall the pellets shrink the tumour. But as with any treatment there can be side effects.
