I had surgery for rectal cancer in July 2003 (with a permanent colostomy), followed by 16 radiation treatments. I was supposed to have 30 treatments, but had to stop because the radiation caused a bowel blockage and then the colon totally shut down (eventually repaired its self). I also had bleeding of the "rectal stump" this past January, due to radiation damage and frequently have mini colon blockage, that I am sure is most likely caused by radiation damage. Is all this damage normal? Are there others out there who also have had radiation damage after colon surgery. Thankfully, I have now been in remsission for one year.
