The lack of a breast cancer risk prediction model tailored to Black women represents a critical gap, given that U.S. Black women, on average, are more likely to have breast cancer at earlier ages and with a worse prognosis than White women. The relatively small number of Black women enrolled in epidemiologic studies of breast cancer has hampered efforts to derive and test models for use in Black women. Now, researchers from Boston University’s Slone Epidemiology Center have developed and evaluated a risk prediction model for breast cancer in U.S. Black women, suitable for use in primary care settings.
