I didn't say you could join my club - you're supposed to be a Zero guy!
OK, I did adjuvant IGRT, link below has the "journey". There isn't much difference in timing between us - my path was so bad we just decided to do it.
What to ask? Wouldn't we all like to know. I guess the big question I never asked, and had to figure out, was what they actually targeted. Since my lymph nodes were clear, it was just the prostate bed. Eighteen months later and a rising PSA, that might prove to have been inadequate, or the micromets were already out. No way to know.
Just be sure you have as much healing done as possible, since my RT pretty much set where I was in stone.
I did not do HT with mine, and there is equal disagreement about that. The uro/surgeon felt then, and still believes that it would not have helped. The RO wanted me to do it, but didn't give any statistics that it really might help.
Dang, got to make room for another member in this club.
