Early detection of colorectal cancer and precursor lesions under colonoscopy, and timely and optimal treatment remain the crucial means for reducing colorectal cancer-related deaths. In this article, we focused on the hot spots in recent years, reviewed the progress of endoscopic diagnosis and treatment of serrated lesions and inflammatory bowel disease (IBD)-related dysplasia, the application of endocytoscopy and the management of early colorectal cancer/precancerous lesions, and provided new prospects for future studies.
