Colon polyps are growths on the lining of the colon or rectum. The colon and the rectum are parts of the large intestine. It is all part of the digestive system.

The two most common kinds of polyp are:

  • Adenomatous polyps—which are pre-cancerous and can become larger over time and may develop into cancer
  • Hyperplastic polyps—do not increase in size and only rarely become cancerous

The cause of most colon polyps is unknown. It may be partly due to hereditary factors.

There are certain genetic conditions, such as familial adenomatous polyposis and Peutz–Jeghers syndrome, which cause many polyps to form.
