Overweight and obesity is associated with increased risk of several cancers, including uterine, kidney, oesophageal, gallbladder, bowel, pancreas and breast cancers.
Incidence of some overweight- and obesity-related cancers including uterine, kidney and bowel cancer is increasing, at least partly due to increasing prevalence of overweight and obesity. Cancer incidence is expected to rise further if current trends in overweight and obesity prevalence persist.
Overweight and obesity are leading risk factors for death in the world. Obesity caused an estimated 6% of deaths in England in 1998; this proportion has likely increased as the prevalence of overweight and obesity has increased. Overweight and obesity causes a (conservatively) estimated 5% of cancer cases in the UK each year.
