Application Of The 2015 American Cancer Society Screening Mammography Guidelines: Risk Assessment For Women Ages 40-44

1557Background: The new ACS screening mammography guidelines suggest that only women with an above average risk require mammography screening between ages 40-44 (≥15% lifetime risk of breast cancer and/or ≥5% risk of BRCA mutation). In addition, the ACS recommends yearly MRI if the lifetime risk is ≥20%. We previously found that 50% of women ages 40-44 who were evaluated at an academic breast surgery practice would be eligible for mammograms, MRI, and/or genetic testing. Here, we sought to determine these numbers at a community breast imaging center, which we assumed would be a cohort more representative of the general population. Methods: Under IRB approval, we reviewed a database from 10/1/2015 - 12/28/2015 of patient-reported risk factors and family history at a community breast imaging center. We excluded all men, and women with a history of breast cancer. Using Tyrer Cuzick, Claus, or BRCAPRO, those with a ≥15% lifetime risk of breast cancer or ≥5% risk of BRCA mutation (eligible for genetic testing)...
