More than 50% of cancers could be prevented if people simply change lifestyles, according to Graham Colditz, PD, DrPH, from the Washington University School of Medicine in St. Louis, Missouri at the Union for International Cancer Control (UICC) World Cancer Congress 2012.

Among the “biggest buys” from lifestyle intervention is smoking cessation. One third of cancer in high–income countries is caused by smoking.

Being overweight or obese causes approximately 20% of cancers today. If people could maintain a healthy body mass index (BMI), the incidence of cancer could be reduced by approximately 50% in 2 to 20 years.

Poor diet and lack of exercise are each associated with about 5% of all cancers. Improvement in diet could reduce cancer incidence by 50% and increases in physical activity could reduce cancer incidence by as much as 85% in 5 to 20 years.
