The Continuous Update Project and Second Expert Report identified obesity as a major independent risk factor for cancer.
A separate analysis was conducted for those cancers where there is strong evidence that excess weight increases cancer risk. The results are shown separately for men and women.
The table shows separate estimates on how much cancer could be prevented by being a healthy weight for men and women. The combined estimates for men and women were 21% for US, 17% for UK, 14% for Brazil and 11% for China.
Using numbers of new cases of cancer diagnosed annually from GLOBOCAN 2012 for both men and women combined this translates to about 116,000 cases of cancer in the USA, about 23,000 for the UK, about 20,000 for Brazil and about 104,000 for China being preventable if everyone had a healthy weight.
