Breast cancer mortality rates have declined in the United States and in Wisconsin. We examined racial differences in mortality trends among black and white women in Wisconsin and the United States from 1979 to 1996. During this time period, mortality rates increased 10% among black women and decreased 7% among white women in Wisconsin. These trends were similar nationally, with an 18% increase among black women and a 3% decrease among white women. The black:white gap in mortality increased among women of all ages--especially among women under age 55. The increasing racial disparity in breast cancer mortality may result from differences in trends in incidence and survival among black women. More research is needed to understand the underlying causes of the disparity in breast cancer mortality between black and white women.
美国和威斯康星州的乳腺癌死亡率均有所下降。我们研究了1979年至1996年期间威斯康星州以及美国黑人和白人女性死亡率趋势的种族差异。在此期间，威斯康星州黑人女性的死亡率上升了10%，白人女性的死亡率下降了7%。全国范围内的趋势与之相似，黑人女性的死亡率上升了18%，白人女性的死亡率下降了3%。各年龄段女性中，黑人与白人的死亡率差距都在增大——尤其是55岁以下的女性。乳腺癌死亡率方面不断增大的种族差异，可能是由于黑人女性在发病率和生存率趋势上存在差异。需要开展更多研究，以了解黑人和白人女性乳腺癌死亡率差异的根本原因。
