Colonoscopy: Any abnormality identified during colonoscopy should be sampled and submitted for pathologic evaluation.

Colonoscopy: Usually there is no biopsy if this is done for screening (to rule out polyps or cancer) and if the doctor does not see anything. However, if the colonoscopy is done for symptoms like diarrhea or bleeding or because the patient has a history of colitis, then the doctor might take some sample biopsies to rule out things that can only be seen under the microscope (microscopic colitis or dysplasia)
