Calculator for breast cancer risk assessment

Calculator for an approximate assessment of breast cancer risk according to the Gail model. The model uses a woman's personal medical and reproductive history and family history of breast cancer (mother, sisters, daughters) to estimate the absolute risk of breast cancer, i.e. the chance or likelihood of developing invasive breast cancer within a defined age interval. The calculator cannot accurately estimate breast cancer risk for:
- Women who carry a BRCA1 or BRCA2 mutation.
- Women with a prior history of invasive or in situ breast cancer (lobular carcinoma in situ or ductal carcinoma in situ)
Although a woman's risk can be estimated accurately, these predictions do not allow precise determination of which woman will develop breast cancer. Some women who do not develop breast cancer have higher risk estimates than some women who do develop breast cancer.
