Small Intestine Cancer

Small Intestine Cancer - A rare cancer that begins in the tissues of the small intestine. The longest section of the gastrointestinal (digestive) tract, the small intestine (or small bowel) connects the stomach to the large intestine. The small intestine is divided into three sections: the duodenum, jejunum, and ileum. Most small intestine cancers develop in the duodenum. There are five types of small intestine cancer, including adenocarcinomas (the most common type), sarcomas, carcinoid tumors, gastrointestinal stromal tumors, and lymphomas. Small intestine cancer has been linked to diets high in fat, and a health history of Crohn disease or celiac disease.
