Black women die of breast cancer at a much higher rate than white women. Recent studies have suggested that this racial disparity might be even greater in Chicago than the country as a whole. When data describing this racial disparity are presented they are sometimes attributed in part to racial differences in tumor biology. Vital records data were employed to calculate age-adjusted breast cancer mortality rates for women in Chicago, New York City and the United States from 1980-2005. Race-specific rate ratios were used to measure the disparity in breast cancer mortality. Breast cancer mortality rates by race are the main outcome. In all three geographies the rate ratios were approximately equal in 1980 and stayed that way until the early 1990s, when the white rates started to decline while the black rates remained rather constant. By 2005 the black:white rate ratio was 1.36 in NYC, 1.38 in the US, and 1.98 in Chicago. In any number of ways these data are inconsistent with the notion that the disparity in black:white breast cancer mortality rates is a function of differential biology. Three societal hypotheses are posited that may explain this disparity. All three are actionable, beginning today.
黑人女性死于乳腺癌的比率远高于白人女性。最近的研究表明，这种种族差异在芝加哥可能比整个国家更为明显。当呈现描述这种种族差异的数据时，有时部分归因于肿瘤生物学中的种族差异。利用生命记录数据，计算了 1980 年至 2005 年期间芝加哥、纽约市和美国女性的年龄调整乳腺癌死亡率。种族特异性率比用于衡量乳腺癌死亡率的差异。乳腺癌死亡率是主要结果。在所有三个地区，种族比在 1980 年大致相等，并保持这种状态直到 20 世纪 90 年代初，当时白人死亡率开始下降，而黑人死亡率保持相对稳定。到 2005 年，纽约市的黑/白比率为 1.36，美国为 1.38，芝加哥为 1.98。从许多方面来说，这些数据与黑/白乳腺癌死亡率差异是生物学差异的结果这一观点不一致。提出了三个可能解释这种差异的社会假设。从今天开始，所有三个假设都可以采取行动。
