Although many people know the health risks that come with obesity, new research finds that it may increase the risk of cancer.

According to a study published in the journal Cell, obesity can lead to an increased risk of liver cancer. Researchers believe if they could curb obesity, they may be able to reduce cancer deaths by as many as 90,000 a year.

The study reveals that obese people have a 4.5-fold greater risk for developing liver cancer and a 1.5-fold greater risk of overall cancers.

Researchers believe that physicians spend too much time focusing on other obesity risks such as type 2 diabetes and cardiovascular disease.

“Doctors always worry about our weight, but the focus is often on cardiovascular disease and type 2 diabetes, both of which can be managed pretty well with existing drugs,” said researcher Michael Karin. “However, we should also worry about elevated cancer risk.”

For people who are worried about their extra pounds, adopting an alkaline diet of fruits, vegetables and whole grains may help control weight gain.
