Small Intestine Cancer
There are five types of small intestine cancer: adenocarcinoma, sarcoma, carcinoid tumors, gastrointestinal stromal tumor, and lymphoma. The National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program estimates that 11,110 people will be diagnosed with small intestine cancers in the United States and 1,700 deaths from these cancers in 2020.
Adenocarcinoma starts in glandular cells in the lining of the small intestine and is the most common type of small intestine cancer. Most of these tumors occur in the part of the small intestine near the stomach. They may grow and block the intestine.
Eating a high-fat diet and having Crohn disease and celiac disease increase the risk of developing small intestine cancer. In addition, having familial adenomatous polyposis (FAP) is a risk factor for this form of cancer.Small Intestine Cancer Treatment (PDQ®)
