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


Report: Half of Cancer Deaths are Preventable

Almost one of every two people born today will develop cancer, but more than half of all cancer deaths are preventable, according to a major report released today on the state of cancer progress.AICR_trefoil

The American Association for Cancer Research (AACR) report estimates that 580,350 Americans will die from cancer this year. More than half of these cancer deaths link to preventable causes, including smoking, obesity, poor diet, drinking alcohol, inactivity, and sun exposure.

This report’s section on preventability aligns with AICR findings that lifestyle matters when it comes to lowering cancer risk.

Decades of funding and analyzing the research on diet, body fat, and physical activity have led to some clear conclusions on cancer prevention and survivorship. AICR estimates that staying a healthy weight, eating a healthy diet, and daily activity can prevent over a third of US cancer cases. Continue reading
