In an analysis of women with early breast cancer, Black women had higher rates of obesity and other health conditions that can affect survival, compared with white women. The findings are published early online in CANCER, a peer-reviewed journal of the American Cancer Society (ACS).
Obesity is a known risk factor for various cancers, and its rise over the past few decades has contributed to a rise in breast cancer rates that is greater in Black women than white women. At the same time, as breast cancer mortality rates have declined, the decline has been less pronounced in Black women, producing a 40% mortality gap.
To investigate further, Kirsten Nyrop, PhD, of the University of North Carolina at Chapel Hill, and her colleagues analyzed information concerning 548 patients treated at their hospital for early breast cancer. The team found that 62% of Black patients and 33% of white patients fell within the obese weight range, and higher percentages of Black women had obesity-related comorbidities, such as hypertension, diabetes, and high cholesterol, than white women. Yet, despite significant differences in the prevalence of obesity and comorbidities, there were no differences between Black and white patients in treatment decisions with regard to type of surgery, chemotherapy, radiation, or endocrine therapy.

Dr. Nyrop noted that rates of many cancers that are impacted by obesity are higher in Black women as are rates of numerous obesity-related conditions such as diabetes and hypertension. "As the COVID-19 pandemic has glaringly underscored, there is an urgent need to address the systemic and socioeconomic aspects of obesity that disproportionately affect minority communities in the U.S. if we are to reverse health disparities."
