More Cancers May Be Linked to Obesity

Obesity may increase the risk of developing many types of cancer, a study suggests. Weight gain has been suspected to increase the risk of a few cancers for some time. These include colon and breast cancer. But the new study adds other cancers to the list. They include cancers of the esophagus, thyroid, kidney, uterus and gall bladder. The study compiled data from 141 previous studies on four continents. Weight gain of about 30 pounds within 15 years was linked to the higher cancer risk. The Associated Press wrote about the study February 15. It was published in the journal Lancet.
