Cancer preventability estimates
AICR's research report includes estimates of how much cancer could be prevented through diet, activity and weight management. For the most common US cancers, nearly one third of cases are preventable through a healthy diet, being physically active and maintaining a healthy weight.
|Cancer Type||New Cases||Percentage Prevented||*Number of Cases Prevented|
|Mouth, Pharyngeal & Laryngeal||43,570||63%||27,449|
|TOTAL PREVENTABLE (rounded)
*Estimated and rounded, based on: AICR/WRCF, Policy and Action for Cancer Prevention 2009; Continuous Update Project reports; American Cancer Society, Cancer Facts & Figures 2017.

|Cases Prevented Annually|
- Cancer risk associated with lifestyle factor
- Prevalence of low, moderate and high levels/consumption of lifestyle factor
- Incidence of different cancers
You can read the full methodology used to calculate the estimates in Appendix A of the Policy Report.
Briefly: Estimates were made for lifestyle factors judged to be convincing or probable modifiers of cancer risk in Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective and its continuous updates.Limitations
Evidence for the policy report came partly from two systematic literature reviews that investigated two specific questions: What factors shape the patterns of behavior that affect cancer risk (namely diet, physical activity and body fatness)? And, around the world, what effects have specific interventions had on those patterns of behavior?
The preventability figures are estimates; they are not precise values. They are likely underestimates, as only those cancers judged to have convincing or probable links to lifestyle factors are included.
For the 2009 Policy Report, these estimates were based on GLOBOCAN 2002 data. Those original estimates have been updated with the most recent global incidence data from GLOBOCAN* on cancer rates.
