Obesity-related cancers on the rise in the U.S.
There's a link between obesity and 40 percent of all the cancers diagnosed in the United States, health officials reported Tuesday. That doesn't mean too much weight is causing all these cancer cases, just that there's some kind of still-to-be explained association, according to the U.S. Centers for Disease Control and Prevention. Still, the study findings suggest that being obese or overweight was associated with cancer cases involving more than 630,000 Americans in 2014, and this includes 13 types of cancer.
"That obesity and overweight are affecting cancers may be surprising to many Americans. The awareness of some cancers being associated with obesity and overweight is not yet widespread," Dr. Anne Schuchat, CDC deputy director, said during a midday media briefing.
Speaking at the news conference, Dr. Lisa Richardson, director of CDC's Division of Cancer Prevention and Control, said early evidence indicates that losing weight can lower the risk for some cancers. According to the new report from the CDC and the U.S. National Cancer Institute, these 13 obesity-related cancers made up about 40 percent of all cancers diagnosed in the United States in 2014.
The World Cancer Research Fund estimates that "20 percent of all cancers in the United States are caused by a combination of excess body weight, physical inactivity, excess alcohol, and poor nutrition. The American Cancer Society is currently doing its own extensive calculation of the numbers and proportions of cancer cases attributable to excess body weight, the results of which will be published soon," he said.
