Bowel polyps

Also called Colon polyps, Colorectal polyps, or Adenomas

Bowel polyps are small growths on the lining of the large bowel or rectum. They are very common, especially after 50, and usually cause no symptoms. Most are harmless, but some types can slowly turn into bowel cancer over many years, so they are usually removed when found.

What it is

Polyps are often found during bowel screening or a colonoscopy done for another reason. They can usually be removed painlessly during the colonoscopy.

After polyps are removed, you may need repeat colonoscopies at intervals based on how many there were, their size and type.

Common signs

  • Usually no symptoms
  • Sometimes blood or mucus in the stool
  • Occasionally a change in bowel habit

How it is usually diagnosed

  • Colonoscopy
  • Stool test (FIT) as part of screening
  • Lab examination of removed polyps

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Colonoscopy reports with the number and size of polyps
  • Pathology reports for each removed polyp
  • The date your next colonoscopy is due

Questions to ask your doctor

  • What type of polyps were they?
  • When do I need my next colonoscopy?
  • Should my relatives be screened?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Heavy bleeding from the bottom after a polyp removal
