This section outlines logic paths for screening/surveillance of patients who are at increased risk of developing colorectal cancer. These include screening of assymptomatic patients at increased risk for colorectal cancer (e.g. those with a family history of colorectal cancer), surveillance based on personal history (e.g. patients with a personal history of precancerous polyps), or surveillance as part of disease management (e.g. patients with inflammatory bowel disease). The guidelines supporting recommendations for colorectal cancer screening for increased-risk populations are population-specific.
