Small bowel cancer is an uncommon type of cancer that occurs in the small intestine. Your small intestine, which is also called the small bowel, is a long tube that carries digested food between your stomach and your large intestine (colon).

Types of small bowel cancer include:

  • Adenocarcinoma
  • Sarcoma, including gastrointestinal stromal tumor (GIST)
  • Carcinoid tumors
  • Lymphoma

What treatment options are best for you depend on the type of small bowel cancer you have and its stage.
