Breast Cancer Risk Calculator

IMPORTANT

This calculation tool may use data based on race information while evaluating certain risk factors. The calculation can also be performed by selecting race as “Unknown”; however, in this case the system uses the “White” category as the default. Therefore, it is recommended that this situation be taken into consideration when interpreting the results.
