Preventability for Diet, Weight, Physical Activity
Updated estimates of cancer preventability – the population-attributable fraction, or PAF% – through diet, activity and weight management. For the most common US cancers, close to 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||44,320||63%||27,922|
*Rounded, based on AICR/WRCF, Policy and Action for Cancer Prevention 2009; Continuous Update Project reports; American Cancer Society, Cancer Facts & Figures 2018.
Preventability estimates are important to help policy-makers assess the impact of different approaches to reduce cancer risk.
AICR/WCRF preventability estimates are calculated using information on:
- Cancer risk associated with lifestyle factor
- Prevalence of low, moderate and high levels/consumption of lifestyle factor in each country
- US incidence of different cancers
The methods used to calculate the estimates can be found in Appendix A of the Policy Report.
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.
These 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.
