Understanding Breast Cancer Risk
About the Gail Model
This calculator uses the Gail model, developed by Dr. Mitchell Gail and colleagues in 1989. It's a statistical tool that estimates a woman's risk of developing invasive breast cancer over the next 5 years and over her lifetime.
Risk Factors Considered
- •Current age and race/ethnicity
- •Age at first menstrual period
- •Age at first live birth or nulliparity
- •Number of previous breast biopsies
- •History of atypical hyperplasia
- •Family history of breast cancer
Screening Guidelines
Ages 40-44
- •Option to begin annual mammograms
- •Discuss benefits and risks with doctor
- •Consider family history
Ages 45-54
- •Annual mammograms recommended
- •Clinical breast exams
- •Breast self-awareness
Ages 55+
- •Mammograms every 1-2 years
- •Continue as long as good health
- •Life expectancy 10+ years
High-Risk Considerations
Women at high risk (≥1.67% 5-year risk) may benefit from:
- • Earlier mammogram screening (before age 40)
- • Additional imaging (breast MRI, ultrasound)
- • Enhanced surveillance protocols
- • Risk reduction strategies (chemoprevention)
