Quick Answer: Can tumors be removed during colonoscopy?

What happens if a tumor is found during a colonoscopy?

Usually if a suspected colorectal cancer is found by any screening or diagnostic test, it is biopsied during a colonoscopy.

Can a doctor tell if polyp is cancerous during colonoscopy?

A colonoscopy is considered positive if the doctor finds any polyps or abnormal tissue in the colon. Most polyps aren’t cancerous, but some can be precancerous. Polyps removed during colonoscopy are sent to a laboratory for analysis to determine whether they are cancerous, precancerous or noncancerous.
