Answer

The goal of colorectal cancer screening is to decrease mortality through diagnosis and treatment of precancerous lesions (adenomatous colon polyps) and early curable cancerous lesions. The evidence for the importance of early detection and removal of colorectal polyps in preventing development of invasive cancer is mostly indirect but has been corroborated by data from many trials.
