The table shows estimates for each cancer for the four countries. Totals are given for the 13 cancers (common cancers) studied as well as for all cancers.
The estimate for all cancers assumes that cancers not listed in the tables are not related to cancer risk.
For the 13 common cancers about 29 per cent of cases in the USA are preventable through a healthy diet, being physically active and maintaining a healthy weight. The estimates for the other countries are 29 per cent for the UK, 22 per cent for Brazil and 19 per cent for China.
Using numbers of new cases of cancer diagnosed annually from GLOBOCAN 2012 this translates to about 320,000 preventable cases of cancer in the USA, about 72,000 for the UK, 66,000 for Brazil and about 460,000 for China.
The updated figures confirm that about a third of the most common cancers in higher-income countries and about a quarter in lower-income countries could be prevented through eating healthily, being physically active and maintaining a healthy weight.
These figures are estimates and not precise values. They may be underestimates as only cancers with evidence judged to be convincing or probable by the Continuous Update Project or Second Expert Report Panels are included.
