Core Tip
Core Tip: Colonoscopy is a powerful tool for colorectal cancer screening, but its wide adoption may incur a large burden on healthcare systems. Risk stratification may be an attractive strategy particularly in resource-constrained settings. Previously developed risk calculators have important limitations including retrospective design and/or inclusion of at-risk individuals such as those with a positive family history. Using 4 easy-to-obtain baseline variables (BMI, smoking, age, and red meat consumption), we present a risk calculator for advanced neoplasia in true average-risk individuals. This simple tool can be used to stratify patients for colorectal cancer screening but requires external validation.
