Racial and Ethnic Disparities in Breast Cancer: A Collaboration Between the American College of Radiology Commissions on Women and Diversity and Breast Imaging.

Since the 1980s, the mortality rate from breast cancer in the United States has dropped almost 40%. The quality of life and survival gains from early detection and improved treatment have not been shared equally by all ethnic groups, however. Many factors, including social determinants of health, unequal access to screening and oncologic care, and differences in incidence, tumor biology, and risk factors, have contributed to these unequal breast cancer outcomes. As breast radiologists approach their own patients, they must be aware that minority women are disproportionately affected by breast cancer at earlier ages and that non-Hispanic Black and Hispanic women are impacted by greater severity of disease than non-Hispanic White women. Guidelines that do not include women younger than 50 and/or have longer intervals between examinations could have a disproportionately negative impact on minority women. In addition, the COVID-19 pandemic could worsen existing disparities in breast cancer mortality. Increased awareness and targeted efforts to identify and mitigate all of the underlying causes of breast cancer disparities will be necessary to realize the maximum benefit of screening, diagnosis, and treatment and to optimize quality of life and mortality gains for all women. Breast radiologists, as leaders in breast cancer care, have the opportunity to address and reduce some of these disparities for their patients and communities.
