Screening and Surveillance Colonoscopy

Colorectal cancer is a major cause of worldwide morbidity and mortality. As such, there are many guidelines and recommendations set forth by various medical societ‐ ies regarding colonoscopy for screening and surveillance. The universal goal of these guidelines is to reduce colorectal cancer prevalence and mortality. Recommendations for colorectal cancer screening and surveillance using colonoscopy vary slightly be‐ tween medical society guidelines and are often dictated by some combination of age, known disease severity, length of time since last study, family history, and comorbid conditions.
