Research progress in colorectal cancer screening

Abstract

The incidence of colorectal cancer is high threatening human health. About 60%~70% cases of CRC are derived from colorectal polyps, which can be treated by endoscopic electrotomy to prevent the possibility of canceration. Therefore, in the prevention and treatment of CRC, the role of screening is of great significance. CRC screening methods include the most commonly used fecal occult blood test (FOBT) and the more sensitive fecal immunochemical test (FIT), cost-effective fiber sigmoidoscopy and colonoscopy, CT colonoscopy (CTC), and fecal DNA testing and immature CRC hematology screening. In this paper, the CRC screening technologies were reviewed, including the principles, characteristics and the latest research progress to provide a theoretical basis for the application and development of CRC screening technology.
