- Early-onset cancers expose a measurement gap: Most datasets miss early-life exposures, leaving the first decades of life “largely invisible” in cancer research.
- Current methods underestimate risk and preventability: Simplified, single-time-point measures (e.g., BMI, alcohol intake) fail to capture timing, intensity, and trajectories of exposure.
- Cancer risk is a life-course process: Accumulating exposures—from in utero through adulthood—interact with biology to shape susceptibility over time.
- New frameworks are needed: The authors propose tissue ecosystem–based discovery, biological state–based risk prediction, and dynamic models of preventability.
- Near-term progress depends on data integration: Linking cohorts, EHRs, and biobanks is the most practical path to studying life-course cancer risk at scale.
