A new study from the Washington University School of Medicine in St. Louis reports that diabetes and excess weight lead to nearly 6% of cancers worldwide. For this report, researchers analyzed health data from 175 countries. They found that 5.6% of new cancer cases in 2012 were a result of diabetes and high BMI. Obesity alone led to 4% of new cancer cases, and diabetes alone led to 2% of new cancer cases.
It is estimated that over 422 million adults around the world have diabetes, and more than 2 billion are obese or overweight. With these increasing cancer risk factors, efforts need to focus on screening and prevention.
These findings were published in The Lancet Diabetes & Endocrinology on November 28, 2017.
