A new study by the International Agency for Research on Cancer (IARC), the specialized cancer agency of the World Health Organization (WHO), shows that nearly half a million new cancer cases per year can be attributed to high body mass index (BMI).
The study, published today in The Lancet Oncology, highlights that overweight and obesity have become a major risk factor, responsible for an estimated 3.6% (481 000) of all new cancer cases in 2012.
