Answer

Because early-stage colon cancer is typically asymptomatic, screening plays a major role in the diagnosis of curable cancerous lesions, as well as the detection of precancerous lesions (adenomatous colon polyps). The decline in colorectal cancer incidence and death rates over recent decades has largely been attributed to widespread adoption of screening. [24]
