Abstract
Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype more frequently diagnosed among non-Hispanic Black women than other racial and ethnic populations in the US.1 It is unknown, however, whether the racial and ethnic disparity in TNBC risk differs by state, limiting our ability to inform state-level health policy for breast cancer equity. Prior studies on state-level TNBC incidence were limited by lower geographical coverage,1-3 lack of consideration of race and ethnicity,1 or exclusion of racial and ethnic minority groups other than Black and White populations.2,3 Furthermore, none of these studies reported on state variations in racial and ethnic disparities in TNBC rates. This study examined state variations in TNBC incidence rates (IRs) between and within racial and ethnic populations.
