Screening tests play a key role in detecting polyps before they become cancerous. These tests can also help find colorectal cancer in its early stages, when you have a good chance of recovery.

Screening methods include:

  • Colonoscopy
  • Virtual colonoscopy (CT colonography)
  • Flexible sigmoidoscopy
  • Stool-based tests


Your doctor is likely to remove all polyps discovered during a bowel examination. The options for removal include:

  • Removal with forceps or a wire loop (polypectomy)
  • Minimally invasive surgery
  • Colon and rectum removal (total proctocolectomy)
