Obesity raises risk of developing Cancer

November 5, 2009 12:00:00 AM PST
Obesity causes more than 100,000 cases of cancer in the United States every year. And the number will likely rise as Americans gain more weight. That's according to a new study by the American Institute for Cancer Research. Among the types of cancer most strongly linked to excessive body fat are: breast, endometrial, esophageal, pancreatic and kidney.

Nearly a third of all the adults in America are obese, meaning they are nearly 30 or more pounds over a healthy weight. Cancer is the second-leading cause of death in the United States after heart disease.

The American Cancer Society projects that 1.47 million people will be diagnosed with cancer this year and 562,000 will die from it.
