I had a colonoscopy about
12 weeks after my final radiation treatment. I did not have any problems and a benign polyp was removed. I let the doctor know that I had just completed raditation treatment and that a portion of it was "full pelvic" before getting the exam. The report came back as clean with a notation that the lower bowel had multiple "angio ectasias". I never found this term as shown but the best I could determine is that this was stiffening of blood vessels in the intestinal track. This can occur even without radiation and can cause bleeding. So far, I have seen no evidence of this either.
Best thing is to ask radiologist and the doctor who will do the colonoscopy for advice. Theirs is professional and mine is anecdotal.
Best of luck to you.
