What is duodenal cancer?

Duodenal cancer is a mass of irregular, fast-growing cells (tumor) in the first portion of your small intestine. This tumor may prevent the intestine from properly digesting food and block food from passing through your intestines.

In early stages, you may have no symptoms of duodenal cancer. If the intestinal tumor grows, you may have symptoms that affect your digestive system, such as nausea, constipation or abdominal cramps.
