TUESDAY, Oct. 3, 2017 (HealthDay News) -- 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.
The 13 cancers include: brain cancer; multiple myeloma; cancer of the esophagus; postmenopausal breast cancer; cancers of the thyroid, gallbladder, stomach, liver, pancreas, kidney, ovaries, uterus and colon, the researchers said.
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.
Although the rate of new cancer cases has decreased since the 1990s, increases in overweight and obesity-related cancers are likely slowing this progress, the researchers said.
Of the 630,000 Americans diagnosed with a cancer associated with overweight or obesity in 2014, about two out of three occurred in adults aged 50 to 74, the researchers found.
Excluding colon cancer, the rate of obesity-related cancer increased by 7 percent between 2005 and 2014. During the same time, rates of non-obesity-related cancers dropped, the findings showed.
In 2013-2014, about two out of three American adults were overweight or obese, according to the report.
For the study, researchers analyzed 2014 cancer data from the United States Cancer Statistics report and data from 2005 to 2014
