Increased Breast Cancer Risk Associated With Greater Fat Intake
: "Eating a high-fat diet may lead to an increased risk of invasive breast cancer in postmenopausal women, according to a study in the March 21 issue of the Journal of the National Cancer Institute.
Although environmental and animal studies have suggested that greater fat consumption may increase the likelihood of developing breast cancer, the results of epidemiologic studies have been inconclusive.
The researchers found that doubling fat intake, from 20 percent to 40 percent, was associated with a 15 percent increase in breast cancer risk. The increase in risk was similar for all types of fat—saturated, monounsaturated and polyunsaturated."
