The Hindu : Health / Medicine & Research : High-fat diet raises risk of breast cancer: study: "Researchers from the University of California at Davis found that a diet linked to obesity and harmful metabolic changes stimulated early breast growth and led to abnormal tissues in the breast that may produce breast cancer.

Scientists fed newly weaned mice a diet containing a fatty acid called 10,12 CLA which can trigger metabolic syndrome, a condition linked to obesity, diabetes and heart disease, the Daily Mail reported. The fatty acid is present in hydrogenated fats, widely used in the manufacture of biscuits, cakes and processed foods.

Giving female mice the 10,12 CLA stimulated growth of their mammary ducts. This was despite the young animals lacking the hormone oestrogen, believed to be vital to female reproductive development.

In some animals, the altered diet also resulted in the kind of abnormal cell growth that can lead to breast cancer."
