While it’s nothing new that Black women have a lower overall rate of breast cancer than their White counterparts, a new study concludes that they are three times more likely than women of other races to develop more aggressive breast cancer. This cancer is also more likely to return after treatment and has a less favorable outcome. The study, which appears in the journal Breast Cancer Research, found that Black women are three times more likely to acquire something called a triple negative tumor, which is diagnosed before or after age 50 regardless of weight. The higher prevalence of these triple negative tumors in all age and weight categories likely contributes to the unfavorable breast cancer prognosis, the study shows.
