Background & AimsColorectal cancer (CRC) incidence and mortality are increasing among persons younger than 50 years old in the United States, but risk factors associated with early-onset CRC (EOCRC) have not been widely studied.MethodsWe conducted a case-control study of US veterans 18 to 49 who underwent colonoscopy examinations from 1999 through 2014. EOCRC cases were identified national registry; free at their baseline 3 follow-up as controls. We collected data on age, sex,...

Colorectal cancer is the third most diagnosed in adults United States. Early detection could prevent more than 90% of colorectal cancer-related deaths, yet one screening-eligible population not up to date with screening despite multiple available tests. A blood-based test has potential improve adherence, detect earlier, and reduce mortality.
