Fancy,
First, let me welcome you to the best site to get info/advice from fellow "affectees".
After my procedure (robotic surgery), the folks on this site were very helpful.
Second, you have to make the decision that is best for you. In my case, the doc felt that the PCA was contained within the capsule. I was not a proponent of radiation. My feelings were to go with surgery.........if my prostate didn't want me, then I didn't want it!
But that was for me! Other folks have made different decisions, and that worked for them.
So, gather all the info you can.......and make the decision that is best for you.
Good luck!
