Causes, Risk Factors, and Prevention TOPICS

Can small intestine adenocarcinoma be prevented?

At this time, there is no known way to prevent most cases of small intestine adenocarcinoma. Since smoking may increase the risk of this cancer, not starting or quitting smoking may reduce the risk for this disease.

People with familial adenomatous polyposis (FAP) can have a very high risk of duodenal cancer. Doctors may suggest that these patients have surgery to remove the duodenum before cancer can develop. The procedure most often used is called a pancreaticoduodenectomy, a major operation that removes the duodenum, part of the pancreas, the gallbladder, the common bile duct, and part of the stomach. This surgery is most often done in patients with FAP who have many polyps in the duodenum and so are at a high risk of getting duodenal cancer. This procedure is discussed in more detail in the “Surgery for small intestine adenocarcinoma” section of this document.
