Pre-menopausal African American Women's Risk

Pre-menopausal African American women have a higher prevalence of basal-like breast tumors than post-menopausal African American and non-African American women, which could contribute to their poorer prognosis, according to a study in the June 7 issue of JAMA.

Breast cancer is composed of an increasing number of recognized biological subtypes. The prognostic importance of this is complicated by many factors, including the observation that differences in clinical outcomes often correlate with race, according to background information in the article. Although breast cancer is less common among African American women, among those who develop it the prognosis is worse. The age-adjusted death rate in the United States from breast cancer in white women is 28.3 deaths per 100,000 compared with 36.4 deaths per 100,000 in African American women. This disparity is particularly pronounced among women younger than 50 years, in whom the death rate is 77 percent higher among African American women compared with white women. Biological differences among breast cancers may reflect genetic influences, differences in lifestyle, or nutritional or environmental exposures.
