High dietary fat, cholesterol linked to increased risk of breast cancer

Elevated fat and cholesterol levels found in a typical American-style diet play an important role in the growth and spread of breast cancer, say researchers at the Kimmel Cancer Center at Jefferson.
The study, published in the January issue of The American Journal of Pathology, examines the role of fat and cholesterol in breast cancer development using a mouse model. The results show that mice fed a Western diet and predisposed to develop mammary tumors, can develop larger tumors that are faster growing and metastasize more easily, compared to animals eating a control diet.
