 Race

White women are more likely to develop breast cancer than black, Hispanic or Asian women are, but black women are more likely to die of the disease because their cancers are found at a more advanced stage. Although some studies show that black women may have more aggressive tumors, it's also likely that the disparity is at least partially due to socioeconomic factors. Women of all races with incomes below the poverty level are more often diagnosed with late-stage breast cancer and more likely to die of the disease than are women with higher incomes. Low-income women often don't receive the routine medical care that would allow breast cancer to be discovered earlier.
