Disparities in Hormone Receptor-Positive Breast Cancer

While the incidence of hormone receptor-positive, HER2-negative (HR + HER2-) breast cancer is lower for Black women compared to White women, the mortality rate is higher. This review highlights available data in four areas of disparities in HR + HER2- breast cancer: risk factors, tumor biology, treatment, and social determinants of health.

Racial disparities persist in a variety of breast cancer-related outcomes in women with HR + breast cancer, despite adjustment for confounders. This emphasizes the multifactorial etiology of disparities in breast cancer outcomes.
