What are the early detection guidelines for those at increased risk for colorectal cancer?

In this update of the colorectal cancer screening guidelines, we have focused on screening in average risk adults and have not reviewed recent literature on colorectal cancer screening or surveillance among individuals at increased and high risk. Individuals at increased risk due to a history of adenomatous polyps, a personal history of curative-intent resection of colorectal cancer, or a family history of either colorectal cancer or colorectal adenomas diagnosed in a first-degree relative before age 60, or high-risk, due to a history of inflammatory bowel disease of significant duration, or the presence of one of two hereditary syndromes should continue to follow recommendations issued previously by the American Cancer Society or USMSTF. The current guidelines update includes tables summarizing the recommendations for those at increased risk.
