Women are less likely to die of breast cancer than they were a decade ago, but not all women are benefiting from that trend. White women saw more of a drop in death rates than black women — 1.9 percent a year from 2010 to 2014, compared to a 1.5 percent decrease for black women, according to a report published Thursday by the Centers for Disease Control and Prevention.

The breast cancer incidence rate among Hispanic women is 28 percent lower than for their non-Hispanic white counterparts. Yet breast cancer remains the leading cause of cancer death for Hispanic women, with an estimated, 2,800 deaths in 2015, according to the American Cancer Society. This may be due to the fact that breast cancer is less likely to be diagnosed at a local stage in Hispanics. Between 2008 and 2012, for example, 57 percent of breast cancers among Hispanic women were found while they were local, that is, still confined to the organ of origin, compared with 65 percent of breast cancers among non-Hispanic white women, the American Cancer Society reports.
