Types of Colorectal and GI Cancer

A diagnosis of GI or colorectal cancer is specific to the part of the body it affects. For instance, if you have cancer of the stomach, you have a type of GI cancer called gastric cancer.

Types of colon, rectal, and GI cancers include:

  • Anal cancer affects the anus, where the digestive tract ends and expels waste.
  • Bowel cancer occurs in the colon, or the large intestine.
  • Colorectal adenocarcinoma affects the cells that line the colon or rectum. This type accounts for about 95 percent of colorectal cancers.
  • Colorectal cancer involves both colon and rectal cancers.
  • Gallbladder cancer affects the gallbladder — a small sac that collects bile from the liver to aid in digestion.
  • Gastric (stomach) cancer occurs in the cells that line the stomach.
  • GI carcinoid tumors are slow-growing cancers that affect the neuroendocrine cells of the GI tract.
  • Islet cell cancer affects the neuroendocrine cells of the pancreas.
  • Rectal cancer starts in the rectum — the last few inches of the large intestine.
  • Small intestine cancer forms in the small intestine, the part of the bowel between the stomach and the colon.
