Hypertension, Use of Antihypertensive Medications and Breast Cancer Survival Among Black Women

Using 2,474 invasive breast cancer cases in the Black Women's Health Study, the authors examined how hypertension and antihypertensive medication use relate to breast cancer survival. For ER+ disease, treated hypertension was strongly inversely associated with breast-cancer death (HR 0.53); for ER− disease, untreated hypertension carried more than double the risk (HR 2.19). Findings suggest treating hypertension may meaningfully improve breast-cancer outcomes for Black women, possibly through regular care engagement or tumor-suppressing drug effects.
