In the US, breast cancer is now not only deadlier among African-American women than white women, incidence rates are equalizing.
In the past, African-American women were less likely to get breast cancer than white women—but that health advantage is fading, according to the new research published yesterday in CA: A Cancer Journal for Clinicians. The research shows that African-American women's risk increased by 0.4%/year from 2008-2012, a much sharper increase than previous years. They also tend to be diagnosed later, when cancers are more likely to have spread.
Also worrisome, the number of African-American women diagnosed with estrogen-positive breast cancer has been climbing—possibly tied to rising obesity rates, according to Carol DeSantis of the American Cancer Society, who led the study.
