The rate of women getting breast cancer and/or dying from breast cancer varies by race and ethnicity.  Most recent data from the Center for Disease Control and Prevention (CDC) as well as the American Cancer Society show that Caucasian women are most likely to be diagnosed with breast cancer.  African-American women, however, are most likely to die from breast cancer.  The graphs below illustrate the most recent data provided from the CDC.

Although white women have higher rates of postmenopausal breast cancer compared to Africa-American women, African-American women have higher rates of premenopausal breast cancer. This may be due, in part, to differences in prevalence rates of some reproductive factors related to breast cancer risk. For example, compared to white women, African-American women tend to have an earlier age at first period, more lifetime periods and higher blood estrogen levels.
