Researchers who calculated cancer death rates in 24 of the largest U.S. cities found that in 13 of them, black women were significantly more likely to die of breast cancer than white women.
That's despite the evidence that white women are more likely than blacks to get breast cancer in the first place.
"It's unfortunate that this disparity exists and we all need to work hard to overcome it," said Marc Hurlbert, one of the researchers on the new study from the Avon Foundation for Women, which funded the report.
"The good news is it's a solvable problem, because some cites are doing better than others," he said.
Of the cities where black women were more likely to die of breast cancer, that disparity ranged from a 24 percent higher risk of death in New York to more than twice the risk of death in Memphis between 2005 and 2007.
