Study: Almost Half a Million Cancers Worldwide Due to Obesity

Almost half a million cancer cases worldwide are due to the rising rates of overweight and obesity, making many of the most common cancers potentially avoidable, says a new study published in The Lancet Oncology.canstockphoto12101428

The study was funded in part by the World Cancer Research Fund (WCRF) International, which AICR is a member. AICR and WCRF now estimate that approximately 122,000 cases of cancers in the US are due to overweight and obesity.

Researchers in The Lancet study calculated that  481,000 – 3.6% – of all new cancer cases in adults worldwide were attributable to high BMI in 2012, the latest global data available.

Obesity-related cancers are more likely to affect women than men, largely due to endometrial and post-menopausal breast cancers, according to the study. In men, excess weight was responsible for 1.9% or 136,000 new cancers in 2012, and in women it was 5.4% or 345,000 new cases. Continue reading


Study on Overweight and Mortality: The Cancer Side

Just when New Years resolutions on weight loss are in full swing comes a large new study that suggests being pudgy may actually help us live longer, even as it finds being extremely obese increases our risk of premature death.Weight_Veggies_canstockphoto1468161

While the study has already spurred plenty of controversy among the experts, when it comes to cancer one point remains clear: having excess body fat increases the risk of seven types of cancers, including colorectal, post-menopausal breast, and endometrial. The more people weigh, the higher the risk.

“This study raises interesting questions about obesity and all-cause mortality,  but for cancer risk the evidence is clear,” said AICR Director of Research Susan Higginbotham, PhD, MPH, RD. “Our expert report and its updates show that body fatness increases the risk of several common kinds of cancer.”

The study was published today in the Journal of the American Medical Association. Continue reading
