Supplemental breast cancer screening after negative mammography in US women with dense breasts.

ABSTRACT: The extent and determinants of supplemental screening among women with dense breasts are unclear. We evaluated a retrospective cohort of 498 855 women aged 40-74 years with heterogeneously or extremely dense breasts who obtained 1 176 251 negative screening mammography examinations during 2011-2019 in the United States. Overall, 2.8% and 0.3% of mammograms had supplemental ultrasound or magnetic resonance imaging (MRI) within 1 year, respectively. Onsite availability was associated with ultrasound (odds ratio [OR] = 4.35, 95% confidence interval [CI] = 4.21 to 4.49) but not MRI (OR = 0.94, 95% CI = 0.85 to 1.04). Facility academic affiliation and for-profit status were inversely associated with supplemental ultrasound (OR = 0.53, 95% CI = 0.49 to 0.57, and OR = 0.83, 95% CI = 0.81 to 0.86,
