The patients with colorectal cancer in Chinese population are increasing, which is a serious threat to human life and health. In order to improve the high incidence, high mortality and low early diagnosis rate of colorectal cancer and promote cancer screening program in China, leading by the National Clinical Research Center for Digestive Disease (Shanghai), relying on Gastrointestinal-Cancer Prevention & Treatment Center Alliance, in conjunction with a number of related societies, we organized multidisciplinary experts including gastroenterology, digestive endoscopy, oncology, health management and endoscopic quality control to jointly develop this consensus. This consensus aims to establish and refine early colorectal cancer screening protocol adapting to our national conditions and guide the screening practice.
