My 69 year old mom had a colonoscopy. dr removed 2polyps but did not send them for biopsy. he recommended 3yrs instead of 5 to repeat colonoscopy. can he determine if its adenomas just by looking at polyps? thanks ?

ANYTIME TISSUE IS SURGICALLY REMOVED FROM A BODY THAN IT IS THE STANDARD OF CARE TO BIOPSY IT. IT COULD BE PRECANCEROUS,CANCEROUS OR NON-CANCEROUS. POLYPS CAN BE ANY OF THE PREVIOUS. NEXT VISIT IN THREE YEARS IS CORRECT. ASK FOR BIOPSY.

The standard of care calls for examination of all tissues removed, from a patient. by a pathologist. Not doing that falls short of the standards of medical practice. If the polyps are benign, a five year interval would be sufficient. If the polyps have been discarded, you need to find a different doctor.
