Small intestine cancer overview

Overview
In oncology, small intestine cancer, also small bowel cancer and cancer of the small bowel, is a cancer of the small intestine. It is relatively rare compared to other gastrointestinal malignancies such as gastric cancer (stomach cancer) and colorectal cancer.

Small intestine cancer can be subdivided into duodenal cancer (the first part of the small intestine) and cancer of the jejunum and ileum (the later two parts of the small intestine).

Several different subtypes of small intestine cancer exist. These include:
 * Adenocarcinoma
 * Gastrointestinal stromal tumor
 * Lymphoma
 * Carcinoid (ileum)
