Location of adenomas and cancer within the colon. The large intestine has been divided into 13 relevant segments. The CMOST model assumes location dependence for the progression and detectability of adenomas and cancers. Colonoscopy reaches the cecum in 95% of cases. Rectosigmoidoscopy is easier to perform but limited in scope and meant to reach the left flexure in the majority of cases
