inflammation of the rectal mucosa lining due to the ionizing effects of radiation therapy
a possible side effect of external beam radiation therapy. Problems can include pain, bowel frequency, bowel urgency, bleeding, chronic burning, or rectal leakage.
Damage which can occur after pelvic radiation. Symptoms may include bleeding, mucous and bloody discharge, spasm of the rectal wall, urgency, and incontinence due to radiation-induced damage to the rectum. Late symptoms result from scarring of the rectal and anal muscles with loss of some of the small blood vessels. The rectum becomes stiff and noncompliant (nonstretchable) and abnormal blood vessels may develop.
Irritation of the rectum caused by radiation therapy. Problems can include pain, bowel frequency, bowel urgency, bleeding, chronic burning, or rectal leakage.
Radiation proctitis (and the related radiation colitis) is inflammation and damage to the lower parts of the colon after exposure to x-rays or other ionizing radiation as a part of radiation therapy. Radiation proctitis most commonly occurs after treatment for cancers such as cervical cancer, prostate cancer, and colon cancer. Radiation proctitis involves the lower intestine, primarily the sigmoid colon and the rectum.
