About the NYU Women’s Health Study

Between 1985 and 1991, the NYU Women's Health Study enrolled 14,274 women at the Guttman Breast Diagnostic Institute in New York City for a study of endogenous hormones (hormones that are naturally produced by the body), diet, and risk of breast cancer. At enrollment, each woman donated a blood sample and completed a questionnaire about health conditions, reproductive history, and dietary habits. Blood samples were stored in -80°C freezers for subsequent laboratory analyses. These blood samples are used to explore biological differences between women who develop disease and women who remain disease-free. Every few years, study participants are followed-up by mail or telephone at which time they are asked to complete a questionnaire to update information on their health conditions and lifestyle. Very strict procedures are in place to ensure that information allowing identification of the NYU Women's Health Study participants is never disclosed.

The National Cancer Institute is the main source of funding of the NYU Women’s Health Study. Over the years, additional funding for specific projects has been provided by the American Cancer Association, the American Heart Association, the Department of Defense, the National Heart, Lung, and Blood Institute, and the Susan G. Komen Foundation.
