The Lancet Oncology

You know that excess weight is hard on your heart, and that obesity and Type 2 diabetes go hand in hand. Now, a new study in The Lancet Oncology adds cancer to the growing list of problems we can blame on our ballooning waistlines.

For the study, researchers gathered body mass index (BMI) data from 2002 for thousands of people in 184 countries. They then examined cancer rates in 2012, focusing on those previously linked to obesity (called high-BMI-related cancers), such as colon, kidney, pancreatic, and postmenopausal breast cancers. Since obesity isn’t thought to directly cause the Big C — only to promote it — the scientists assumed that there’d be a 10-year lag time between being diagnosed with obesity and developing cancer.

Their frightening finding: 3.6 percent of new cancer cases in 2012 (excluding non-melanoma skin cancers) could be attributed to obesity. That translates to about half a million new diagnoses worldwide — and that’s in just a one-year period.
