Yes, having the PSA go to .08 was the push to do additional therapy, but my surgeon and oncologist had mentioned it at the three month date, with the PSA at .01, and my positive margins. The same day I got the .08 news, I had my first Zoladex injection. (Thank God for U.S. healthcare!) I don't know why Zoladex - just went with the doctors recommendation. Two months later I started my radiation treatments.
I remained active for the two years of hormone treatments, and I feel that helped with the fatigue issues. I walk an hour every day, and continue to officiate high school sports. I called them "warm flashes", but they're irritating - suddenly sweating for no good reason at all. Hormones take about 9 months to wear off, so those still persist.
As my surgeon told me as I started radiation, it would probably kill off the nerves he saved, and he was correct. There's still some hope, but kicking cancer and increasing my chances for a longer life are more important.
Bottom line - keep up your spirits. Be thankful that you have second chance options. You appear to have done a lot of reaearch, and that will help as you make your decision. Good luck!
