Gail Model (Relative Risk)
Clinical Context & Background
The Gail Model (Breast Cancer Risk Assessment Tool) estimates a woman's risk of developing invasive breast cancer over the next 5 years and in her lifetime. This calculator computes the Relative Risk (RR) score based on medical history, which is then compared to population averages.
Formula Logic
Relative Risk calculated from Age at Menarche, First Birth, Biopsy Hx, and Family Hx.Reference Data
| Relative Risk (RR) | Interpretation |
|---|---|
| 1.0 | Average Risk |
| > 1.0 | Higher than average risk |
| ≥ 1.67 | High Risk (Consider chemoprevention e.g. Tamoxifen/Raloxifene) |
