A: Women with family history of breast cancer, those considering genetic testing, or anyone seeking comprehensive breast cancer risk assessment.
Q2: How accurate is the Tyrer-Cuzick model?
A: It's one of the most comprehensive models available, incorporating more risk factors than other models, making it particularly useful for women with family history.
Q3: What risk percentage is considered high?
A: Generally, lifetime risk ≥20% is considered high risk, but clinical context and other factors should be considered.
Q4: Can this model be used for men?
A: The Tyrer-Cuzick model is specifically designed for women's breast cancer risk assessment.
Q5: Should medical decisions be based solely on this calculator?
