Abstract

Colorectal cancer (CRC) is the third commonest cancer worldwide. As many CRC patients were identified at advanced stages, screening asymptomatic individuals has substantial clinical benefit. Most CRC arises through recognizable early stage. With the improved understanding of the biology of CRC and precancerous lesion, testing molecular aberrations in stool and blood promises novel screening approaches that are noninvasive, sensitive, and more affordable compared with traditional structural examinations.

Keywords: Colorectal cancer; biomarkers; screening; stool.
