Comprehensive Screening for Women at High Genetic Risk for Developing Breast Cancer

General Purpose: The purpose of our protocol is develop a comprehensive screening protocol for women at high risk for developing breast cancer in the hopes of detecting breast cancer or it's precursor lesions at the earliest possible stage and reducing breast cancer mortality. The following are our specific goals in this endeavor; 1. To assess the sensitivity and specificity of MRI in breast cancer detection in women at high risk compared to mammography 2. To assess the ability of random periareolar fine needle aspiration to detect abnormal ductal cells and to correlate these results with MRI and mammogram findings 3. To assess appropriate screening intervals for BRCA1/2 mutation carriers and women with a \>10% risk of developing breast cancer in ten years The following aims will be outlined in detail under methodology.
