If you are asking all of us, I had a surprisingly good experience with radiation. No pain and the sessions were fast. I did have a little acid reflux afterwards

No experience at all

The new pin point type radiation is wonderful if you have a qualified doctor and a hospital with the latest equipment. After suffering immensely (to the quitting position) with chemo, I sailed through radiation--5 sessions every other day. And the cancer antigen went down to 50 after a short period, still supposed to drop more as radiation takes more time to reveal progress.
