Trans-fats, which are being phased out of food because they clog arteries, may raise the risk of getting breast cancer, European researchers reported on Friday.
They found that women with the highest blood levels of trans-fats had about twice the risk of breast cancer compared to women with the lowest levels.
The higher the levels of trans-fatty acids, the more likely a woman was to have cancer, Chajes and colleagues found.
Women with higher levels of omega-3 fatty acids, being studied for their potential benefits to health, were not any less likely to have breast cancer, the researchers found.
Obese women are more likely to develop breast cancer, among other types of cancer, and high-fat diets are also linked with breast cancer.
