AbstractBreast cancer is the most common noncutaneous malignancy affecting women in the United States, with >245,000 cases diagnosed annually. Breast cancer mortality rates have continued to trend down in the past three decades, yet racial/ethnic disparities persist, with the worst mortality rates seen in Black women. Of note, when compared by race, this downward trend is also trailing in Black women. Survival after breast cancer is mainly driven by factors related to early detection and effective therapy. These factors can be grouped into "biological" such as age, genetic mutations, tumor characteristics; and "social" such as education, income, access to care. There have been studies attributing racial disparities solely to biological factors, and there are those attributing the disparities to social factors alone. Although the exact mechanism is unclear, a relationship between both factors as relates to racial disparities in breast cancer outcomes has been demonstrated. In this report, we review factors contributing to the increased morbidity and mortality for breast cancer in Black women and explore sociological relationships. Facing the worst poverty rates compared with other races, Black women are inevitably more likely to be uninsured, have limited access to quality education, and have fewer financial resources. The goal of this review was to elucidate the complex interplay between biological and social factors contributing to racial disparities in breast cancer outcomes. We conclude by emphasizing the need for interventions made at both local and national levels.
