How Much – and What Kind – of Cancers are Preventable?
The AICR policy report sought to determine how much cancer could be prevented through diet, physical activity and weight management.
|Cancer Type||New Cases||Percentage Prevented||*Number of Cases Prevented|
|Mouth, Pharyngeal & Laryngeal||38,960||63%||24,545|
*Estimated, based on: AICR/WRCF, Policy and Action for Cancer Prevention 2009; Continuous Update Project reports; Rebecca Siegel et al. “Cancer statistics, 2014.” CA: A Cancer Journal for Clinicians Volume 64, January/February 2014.
Preventability estimates were calculated using information on:
- Cancer risk associated with lifestyle factor
- Prevalence of low, moderate and high levels/consumption of lifestyle factor in each country
- Incidence of different cancers in each country
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 the report and its continuous updates, with a few exceptions; thus 12 cancers were included.
Highest versus lowest risk estimates were used for cancer risk. One research study (ideally large and recent) was chosen from those collected as part of the 2007 report and its continuous updates, where the size of effect was representative of all studies. Information on prevalence of lifestyle factors was obtained from national surveys. These two pieces of information were used to estimate preventability for each lifestyle factor.
