There has been so much posted on SEs that you'll just need to do a search to pull hundreds of conflicting posts.
I am almost two years out from adjuvant RT, and can report:
- extreme fatigue (causes problems at work)
- radiation cystitis (periodic bleeding/clots in urine)
- colo-rectal bleeding
- pre-existing 'rhoids got worse
- 4-8 BMs a day, up from 1
- urinary incontinence worsened from my post-surgery situation, and has not gotten any better over time.
My RO said none of that was the fault of radiation, my GP and Uro both said they were commonly seen with RT guys.
Ask again in a couple of years ....
