The risk of health problems that affect the digestive tract increases after treatment with:

Radiation therapy to the abdomen or areas near the abdomen, such as the esophagus, bladder, prostate, or testicles, may cause digestive tract problems that begin quickly and last for a short time. In some patients, however, digestive tract problems are delayed and long-lasting. These late effects are caused by radiation therapy that damages the blood vessels. Receiving higher doses of radiation therapy or receiving chemotherapy such as dactinomycin or anthracyclines together with radiation therapy may increase this risk.
