Colonoscopy has many uses beyond just screening for colon cancer. It allows us to assess the general health of the colon, identify inflammation, and remove pre-cancerous polyps. Inflammatory states may be visible during colonoscopy (Crohn’s disease, ulcerative colitis), or microscopic and visible only on biopsies taken during the procedure (lymphocytic and collagenous colitis).

Place of Procedure:

Georgetown University Hospital
Division of Gastroenterology
