New findings show that eating a high-fat diet beginning at puberty speeds up the development of breast cancer and may actually increase the risk of cancer similar to a type often found in younger adult women.
The research comes from the Breast Cancer and the Environment Research Program at Michigan State University and is published in the current online issue of Breast Cancer Research. (more…)
