Risk Calculator

The U.S. National Cancer Institute (NCI) has developed a risk assessment calculator for women age 35 and over. If you are curious about your risk, then try it out:

Breast Cancer Risk Assessment Tool (Age 35+)

Here is what the tool does not include:
Other risk factors, such as dense breast tissue on a mammogram, a high-fat diet, drinking alcohol, low physical activity, or environmental exposures, are “not included in risk estimates with the Breast Cancer Risk Assessment Tool for three reasons: evidence is not conclusive or researchers cannot accurately determine how much these factors contribute to the calculation of risk for an individual woman, or adding these factors does not increase the accuracy of the tool appreciably.”

“Specific hereditary predispositions for breast cancer, such as inheriting a mutation in either the BRCA1 or BRCA2 gene, are not taken into account in risk estimates with the Breast Cancer Risk Assessment Tool. Although the tool performs well in clinics where women have a strong family history of breast cancer, more specific methods for projecting risk are appropriate if a woman is known to carry a breast cancer-producing mutation in BRCA1 or BRCA2.”
