Excess body weight is responsible for an estimated 544,300 cancers, which is about 3.9% of all cancers in the world, according to research by the American Cancer Society, Imperial College London, and the Harvard T.H. Chan School of Public Health.
Researchers from the American Cancer Society have found that women who spend 6 hours or more of free time sitting per day have a 10% greater risk of getting cancer than women who spend less than 3 hours of free time sitting per day.
