    Race & Ethnic Heritage as a Risk Factor in Breast Cancer

     

    Studies do not explain why, but there are clear differences in breast cancer risk depending on race, ethnicity and nationality.

    • Asian women have a statistically lower risk of breast cancer than other ethnic groups. One explanation that has been suggested for this is diet. The consumption of soy products, fish and plant oils, and other foods from vegetable and fruit groups in the Asian diet may reduce estrogen activity or retard the growth of tumors through a chemical interaction. When Asian women are assimilated into the American/European culture their rates of breast cancer increase.
    • Latino women have a diet high in beans and grains which also tends to inhibit estrogenic activity. This may be part of the reason that the breast cancer incidence in Latinas is lower than that of Caucasian women.
    • In the U.S., white women have a higher incidence rate than African American women - 112 compared to 101 per 100,000 cases. However, among women younger than 45, the reverse is true.
    • African American women are more likely to die from the disease - a phenomenon some researchers have attributed to the fact that African American women are often diagnosed at a later and more advanced stage than white women. Other research suggests that tumors in African American women are more aggressive and respond differently to estrogen.
