A member asked:
Might it be that a colonoscopy prevents colon cancer, or is it simply a screening tool?
A doctor has provided 1 answer
Yes it can: Colonoscopy is done to look for polyp which are precursors of cancer. So if the polyp is removed before it becomes cancerous, then we have prevented development of colon cancer.
