Radiation colitis is injury to the colon caused by radiation therapy.[1] It is usually associated with treatment for prostate cancer or cervical cancer.[1] Common symptoms are diarrhea, a feeling of being unable to empty the bowel,[2] gastrointestinal bleeding, and abdominal pain.[1]
If symptoms of radiation colitis onset within 60 days of exposure to radiation, it is referred to as acute; otherwise, it is classified as chronic.[1] Acute radiation colitis may onset within a few hours of radiation exposure, and may clear up within two or three months after radiation ends.[1] Between 5 and 15% of individuals who receive radiation to the pelvis may have chronic radiation colitis.[1] Radiation therapy can also affect the bowel at the small intestine (radiation enteritis) or the rectum (radiation proctitis).[2]
