Early-Onset Colorectal Cancer: A Review of Current Insights and a Call for Action

While the incidence of colorectal cancer (CRC) in patients above 50 years old has been decreasing over the last several decades, the incidence of CRC among younger patients has been increasing. Early-onset CRC (EO-CRC) is known to exhibit distinct characteristics including specific genetic mutations and modifiable risk factors, which warrants tailored screening and management approaches. This review synthesizes current insights on EO-CRC's epidemiological, genetic, molecular, and clinical features, as well as a call for action for future research on prevention and clinical management.
