What are the 7 key risk factors for breast cancer used in the Gail Model?
- Age
- Age at first period (late is better)
- Age at the time of birth of first child (earlier is better)
- Family history of breast cancer (mother, sister or daughter)
- Number of past breast biopsies
- Number of breast biopsies showing atypical hyperplasia
- Ethnicity
The model calculates the risk of developing breast cancer over the next 5 years and also the risk over a lifetime.
