Gail Model of Breast Cancer Risk Assessment

What are the 7 key risk factors for breast cancer used in the Gail Model?

  1. Age
  2. Age at first period (late is better)
  3. Age at the time of birth of first child (earlier is better)
  4. Family history of breast cancer (mother, sister or daughter)
  5. Number of past breast biopsies
  6. Number of breast biopsies showing atypical hyperplasia
  7. Ethnicity

The model calculates the risk of developing breast cancer over the next 5 years and also the risk over a lifetime.
