Sister Study on Environment, Genetics, and Breast Cancer

Are you the sister of a woman who has had breast cancer? If so, you might be interested in the "Sister Study" which the National Institutes of Health is running. The Sister Study will follow women over a ten-year period, and track information about their enviroment and genetics, in an effort to learn more about the factors which raise the risk of developing breast cancer. Women of all races and occupations are encouraged to participate, to help expand our understanding of this disease.
