Has anyone with ulcerative colitis had pelvic radiation, specifically of the prostate bed after surgical prostatectomy? After 13 cancer-free years, doctors are concerned my prostate cancer is trying to return, with a PSA score of .33 after more than a decade of undetectable readings. Numerous scans of various types have not produced a single image of a cancerous mass. Radiation of the prostate bed would normally be a first line of attack, as the assumption is that's where the cells are hiding. However, I also have ulcerative colitis, which is a non-issue for me health wise, but apparently radiation can produce life-changing inflammation of the colitis (ergo, the rectum). Many radiation oncologists won't even attempt prostate radiation with active colitis present, and those who will try are very clear about the risks. Any first-hand knowledge or recent studies would be helpful. Thanks.
