Bowel polyps are abnormal fleshy growths extending from the inner wall of the large bowel (colon and rectum), and left untreated, these can develop into bowel cancer. There are three main types:
* Adenomas and SSLs may develop into cancer in many years, and may occur in patients with rare genetic syndromes.
Bowel polyps are diagnosed by a stool test (faecal occult blood test [FOBT]) and colonoscopy.
Polyps are described by their shape, size, and location in the large bowel. "Sessile" describes flat polyps only slightly raised. Others "pedunculated" are fleshy growths raised up like a mushroom. Most are small, less than 1cm, but can grow multiple centimetres wide.
Bigger polyps and adenomas are more likely to turn into cancer, and there is no way of determining which have this potential, thus why all are removed during colonoscopies via a loop that lassoes around the growth and closed to cut the polyp off.

Bowel cancer is the second most common cause of death from cancer in Australia, and once polyps are removed (polypectomy), this does not eliminate the person's risk of developing further polyps or developing bowel cancer. Future colonoscopies are required for continued monitoring. People with a family hx are at increased risk.
