Why am I having a CT scan after a colonoscopy?

A CT colonography can help identify potentially cancerous areas in people who cannot have a colonoscopy because of other medical reasons. It’s less invasive than a colonoscopy, but you may still need to have colonoscopy or flexible sigmoidoscopy at a later stage so any abnormal areas can be removed or biopsied.

What can a colonography detect?

The major reason for doing CT colonography is to look for polyps or cancers in the colon or rectum. Polyps are small growths on the inside of your bowel. They are usually harmless but some polyps can develop into bowel cancer.

Why do I need a follow up appointment after colonoscopy?

Why is colonoscopy only every 10 years?

Experts say the longer wait can work if the colonoscopy was a high-quality test and the person has no family history of the disease. Other experts, however, say there is risk in waiting longer than 10 years because colonoscopies can miss polyps that can later turn into cancerous cells.
