Colorectal cancer is the leading cause of cancer death in men under 50 in the US, indicating a need for a shift in cancer risk assessment.
Seventy-five percent of 42 countries reported rising early-onset cancer incidences, with Generation X and Millennials facing higher risks.
Current epidemiologic tools are inadequate for understanding early-onset cancers, as most major cohorts begin in midlife.
