      1. BRCA1 or BRCA2 genetic mutation
      2. First degree relative with BRCA1 or BRCA2
      3. Radiation exposure to chest under age 30 years
      4. Lifetime Breast Cancer risk estimated >20%
      5. Other genetic syndromes (and an affected 1d relative)
        1. Li-Fraumeni Syndrome
        2. Cowden syndrome
        3. Bannayan-Riley-Ruvalcaba Syndrome

    2. Breast Cancer evaluation
      1. Define extent of Breast Cancer index lesion
      2. Identify concurrent cancer in contralateral breast
      3. Assess response to Chemotherapy
      4. Define new Breast Cancers in those with implants
      5. Assess for suspected residual cancer post-surgery

  2. Protocol: Breast Cancer Screening
    1. Annual breast mri starting at age 30 in high risk women
    2. Continue Mammograms and Clinical Breast Exams
  3. Efficacy: Breast Cancer Screening
    1. Test Sensitivity: 79% (Mammogram: as low as 33%)
    2. Test Specificity: 90% (Mammogram: 95%)
      1. Higher risk of false positives than Mammogram
