After my surgery and surprising pathology report, the one thing I remember well that my surgeon said, is, "At least it's good that it's sitting in a jar of formaldeheide somewhere!" That statement made a lot of sense to me. The one way to find out how much cancer you have is to take it out. Besides surgery for a broken wrist, this was the first time I had really had my body "invaded". Was I nervous? You bet! I did my Kegal exercises prior to surgery, and after the cathedar was removed. I dreaded the cath more than anything, but since it was put in when I was out of it, all it turned out to be was a nuisance. Has my life changed since the surgery? Another you bet! However, I feel I/they know the degree of my cancer and am following the best thing I can do to give me the best chance at a long and happy life.
Don't eliminate the surgery option. I'm one who am glad that I chose it. Otherwise, if my PSA would have been doing weird things, and I'm sure it would have following EBRT or seeds with my cancer, I would have been freaking out. Keep all options open!
Good luck.
