According to the CDC Breast cancer rates are currently the same between white and african american women. However, African American women are also more susceptible to having a triple negative breast cancer result, which is a type of breast cancer that comes back aggresively often after treatment. Triple negative breast cancer results have limited treatment options. This plays a role in death rates between white woman and african american woman.

Public health agencies are working to make sure that racial disparities are diminished through education of risk factors, and making sure that all woman are screened as recommended.
