About The Study: This study found that initiating fecal immunochemical test screening at age 40 to 49 was associated with further reduction in colorectal cancer (CRC) mortality and incidence compared with starting screening at age 50. These results provide strong empirical support for lowering the CRC screening age, with substantial public health implications.
