Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer death among Louisiana women. The incidence data from Louisiana Tumor Registry were used to calculate breast cancer incidence rates, which were compared with the combined rates from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program. Breast cancer mortality rates for Louisiana were compared with the US death rates from the National Center for Health Statistics (NCHS). Our data revealed that Louisiana women were not at a higher risk for developing breast cancer than women in the SEER areas, but that mortality rates in Louisiana were not correspondingly low. Although the percentage of cases diagnosed at an early stage (in situ and localized) increased in Louisiana from 1988 through 1997, the average in Louisiana was still below the level for the SEER areas (65.9% and 71.6%) in 1993-1997. The rates of in situ breast cancer significantly increased (on average 5.3% for whites per year and 7.1% for blacks), and localized breast cancer also significantly increased (2.6% for whites and 2.5% for blacks), while the incidence of distant stage breast cancer significantly decreased (3.4% for whites and 2.0% for blacks). Compared with white women, black women still were less likely to be diagnosed with early stage breast cancer in 1993-1997 (56.4% and 68.9%). Women residing in the parishes with high percentages of persons in poverty were less likely to be diagnosed with early stage of disease.
乳腺癌是路易斯安那州女性中最常被诊断出的癌症，也是癌症死亡的第二大主要原因。路易斯安那肿瘤登记处的发病率数据被用于计算乳腺癌发病率，并与美国国立癌症研究所监测、流行病学和最终结果（SEER）项目的综合发病率进行比较。路易斯安那州的乳腺癌死亡率与美国国家卫生统计中心（NCHS）的死亡率进行了比较。我们的数据显示，路易斯安那州女性患乳腺癌的风险并不高于SEER地区的女性，但路易斯安那州的死亡率却没有相应地低。尽管1988年至1997年路易斯安那州早期（原位和局部）诊断病例的百分比有所增加，但1993 - 1997年路易斯安那州的平均水平仍低于SEER地区（65.9%和71.6%）。原位乳腺癌的发病率显著上升（白人每年平均上升5.3%，黑人每年平均上升7.1%），局部乳腺癌的发病率也显著上升（白人上升2.6%，黑人上升2.5%），而远处期乳腺癌的发病率显著下降（白人下降3.4%，黑人下降2.0%）。与白人女性相比，1993 - 1997年黑人女性被诊断为早期乳腺癌的可能性仍然较低（分别为56.4%和68.9%）。居住在贫困人口比例高的教区的女性被诊断为疾病早期的可能性较小。
