March is National Colorectal Cancer Awareness Month. That means it's a great time to think about scheduling a colonoscopy if needed.
Colorectal cancer, cancer of the colon and rectum, is the third most common type of cancer in the United States, not counting skin cancers. But many early stage colon cancers can be prevented through a colonoscopy.
According to Gottumukkala S. Raju, M.D., professor in the Department of Gastroenterology, cancer begins as benign polyps within the colon and develops into cancer over years when left untreated, mainly because they are undetected without a colonoscopy.
