Behavioral impact model

If I changed these behaviors, how much would my risk drop?

Pick the behaviors you'd realistically adopt. The model ramps each effect over its biological time-to-benefit, dampens stacked benefits by an independence factor (because risk factors cluster), and projects your lifetime cancer risk against a baseline.

Projected lifetime risk at 10-year horizon
40.0%from 40% baseline · 0.0 pp

Full theoretical potential if every selected behavior reached steady-state benefit: 40.0% (0.0 pp reduction). The shortfall vs the horizon estimate is biological ramp-up time.

Projected risk trajectory

How your lifetime cancer risk drops year-by-year as benefits accumulate.

Contribution per behavior at 10 years

Pick at least one behavior to see its absolute risk reduction.

Method: each behavior carries a steady-state relative risk from the literature, a biological time-to-full-benefit (e.g. 10 years for smoking cessation, 1 year for HPV vaccination), and a difficulty rating. Effects are multiplied with a damping term (the independence factor) that shrinks each successive benefit — because risk factors cluster and real-world effect sizes rarely stack purely. Educational composite; not a validated clinical projection.
