Treatment for childhood cancer can sometimes cause scarring and ongoing problems in the bowel or other parts of the digestive system. The digestive system is also called the gastrointestinal system. It is made up of the organs that break down food for growth and energy.
Am I at Risk?
Other factors that raise risk for digestive problems include:
- a personal history of bowel scarring (adhesions), bowel blockage (obstruction), or chronic graft-versus-host disease of the intestinal tract
- a family history of gallstones or colorectal or esophageal cancer
- tobacco use
What Digestive System Problems Can Occur?
The types of problems that can arise depend on the location of surgery, the radiation treatment field, and the radiation dose. Digestive system problems that can occur include:
- bowl blockage
- scarring and narrowing of the tube that delivers food from the mouth to the stomach
- hardening or scarring of the liver
- chronic diarrhea and stomach pain from ongoing inflammation of the intestines
- colorectal cancer (see related Health Link: “Colorectal Cancer“)
What Are the Symptoms of Digestive System Problems?
Symptoms of digestive system problems include:
- chronic heartburn

Should I Be Screened for Digestive System Problems?
Survivors at risk for digestive problems and those who are having digestive problems should be screening every year at their annual physical examination for problems that affect the digestive system involves an annual physical examination by a qualified health care professional. Blood tests, x-rays, and testing for small amounts of blood in the stool are sometimes needed. If gallstones or gallbladder problems are suspected, you might need an ultrasound. If your colon or esophagus needs to be checked, you might have a colonoscopy or endoscopy.
