Cancer incidence and death rates in the United States are often published at the county or statelevels; examining cancer statistics at the congressional district (CD) level allows decision makers to better understand how cancer is impacting the specific populations they represent.
Cancer incidence data were obtained from the Centers for Disease Control and Prevention's National Program of Cancer Registries and the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. Mortality data were obtained from the National Center for Health Statistics. CD rates were estimated by assigning the county-level age-adjusted rates to the census block and weighting those by the block population proportion of the CD. Those weighted rates were then aggregated over the blocks within the CD to estimate the district rate. Incidence rate estimates for 406 CDs and death rate estimates for 436 CDs were reported according to the boundaries for the 115th Congress of the United States. Maps showing rate estimates for all cancers combined, lung/bronchus, colorectal, female breast, cervical, and prostate cancer are presented by sex and race/ethnicity.
The distribution of cancer incidence and death rates by CDs show similar patterns to those that have been observed at the county and state levels, with the highest cancer incidence and death rates observed in CDs in the South and Eastern regions.
This examination of cancer rates at the CD-level provides data that can be used to inform cancer control strategies at the local and national levels. Displaying the data with the Data Visualizations tool makes it easily accessible to the public and decision makers.
美国的癌症发病率和死亡率通常在县或州层面公布；在国会选区（CD）层面研究癌症统计数据能让决策者更好地了解癌症如何影响他们所代表的特定人群。
癌症发病率数据来自疾病控制与预防中心的国家癌症登记计划以及国家癌症研究所的监测、流行病学和最终结果计划。死亡率数据来自国家卫生统计中心。通过将县级年龄调整率分配到人口普查街区，并按该街区在国会选区中的人口比例加权来估算国会选区发病率。然后将这些加权发病率在国会选区内的街区进行汇总，以估算选区发病率。根据美国第115届国会的选区边界，报告了406个国会选区的发病率估计值和436个国会选区的死亡率估计值。按性别和种族/族裔展示了所有癌症合并、肺癌/支气管癌、结直肠癌、女性乳腺癌、宫颈癌和前列腺癌的发病率估计值地图。
按国会选区划分的癌症发病率和死亡率分布与在县和州层面观察到的模式相似，南部和东部地区的国会选区癌症发病率和死亡率最高。
此次在国会选区层面的癌症发病率研究提供了可用于为地方和国家层面癌症控制策略提供信息的数据。使用数据可视化工具展示这些数据，便于公众和决策者获取。
