Diabetes and high BMI (a BMI over 25 kg/m2) were the cause of 5.6% of new cancer cases worldwide in 2012 - equivalent to 792600 cases, according to the first study to quantify the proportion of cancers attributable to diabetes and high BMI. When considered individually, 544300 cases of cases were attributable to high BMI (equivalent to 3.9% of all cancers), and 280100 were attributable to diabetes (2%).

A large study has found that body mass index, waist circumference and diabetes are all associated with an increased risk for liver cancer. Liver cancer is the sixth most common cancer, and its incidence has tripled since the mid-1970s in the United States.
For the study, in Cancer Research, researchers pooled data from 14 prospective studies with more than 1.5 million participants. After controlling for age, sex, alcohol use, smoking and race, they found that being overweight increased the relative risk for liver cancer by between 21 percent and 142 percent as B.M.I. increased. For each 2-inch increase in waist circumference, the risk of liver cancer increased by 8 percent, even after controlling for B.M.I. And those with Type 2 diabetes had more than double the risk of liver cancer, even among the non-obese.
There was no association of B.M.I. with cancer if the patient had hepatitis, a cause of liver cancer so strong that it overwhelms any other cause. But among those without hepatitis, the increased risk was significant.
“This study underscores that the parallel increase in obesity is part of the increase in liver cancer rates,” said the lead author, Peter T. Campbell, an epidemiologist with the American Cancer Society. “Now we have to accept the fact that obesity and Type 2 diabetes are strongly associated with liver cancer.”
