Colon Cancer and Genetics

In some cases, colon cancer has been found occurring within families. Talk to your doctor about this, or visit the Cancer Genetics Clinic.


Grace H. Elta, M.D., discusses the importance of colonoscopy.


A colonoscopy is a test that allows your doctor to look at the inner lining of your large intestine (rectum and colon). A thin, flexible tube called a colonoscope is used to look at the colon. A colonoscopy helps find ulcers, polyps, tumors, and areas of inflammation or bleeding. During a colonoscopy, tissue samples can be collected (biopsy) and abnormal growths can be taken out. Colonoscopy can also be used as a screening test to check for cancer or precancerous growths in the colon or rectum (polyps).
