This article is the American Cancer Society’s biennial update on female breast cancer statistics in the United States, including data on incidence, mortality, survival, and screening. Over the most recent 5‐year period (2012‐2016), the breast cancer incidence rate increased slightly by 0.3% per year, largely because of rising rates of local stage and hormone receptor‐positive disease. In contrast, the breast cancer death rate continues to decline, dropping 40% from 1989 to 2017 and translating to 375,900 breast cancer deaths averted. Notably, the pace of the decline has slowed from an annual decrease of 1.9% during 1998 through 2011 to 1.3% during 2011 through 2017, largely driven by the trend in white women. Consequently, the black–white disparity in breast cancer mortality has remained stable since 2011 after widening over the past 3 decades. Nevertheless, the death rate remains 40% higher in blacks (28.4 vs 20.3 deaths per 100,000) despite a lower incidence rate (126.7 vs 130.8); this disparity is magnified among black women aged <50 years, who have a death rate double that of whites. In the most recent 5‐year period (2013‐2017), the death rate declined in Hispanics (2.1% per year), blacks (1.5%), whites (1.0%), and Asians/Pacific Islanders (0.8%) but was stable in American Indians/Alaska Natives. However, by state, breast cancer mortality rates are no longer declining in Nebraska overall; in Colorado and Wisconsin in black women; and in Nebraska, Texas, and Virginia in white women. Breast cancer was the leading cause of cancer death in women (surpassing lung cancer) in four Southern and two Midwestern states among blacks and in Utah among whites during 2016‐2017. Declines in breast cancer mortality could be accelerated by expanding access to high‐quality prevention, early detection, and treatment services to all women.

2019 年乳腺癌统计数据

本文是美国癌症协会每两年一次更新美国女性乳腺癌统计数据，包括发病率、死亡率、存活率和筛查数据。在最近的 5 年期间（2012-2016 年），乳腺癌发病率每年略有增加 0.3%，主要是由于局部分期和激素受体阳性疾病的发病率上升。相比之下，乳腺癌死亡率继续下降，从 1989 年到 2017 年下降了 40%，避免了 375,900 例乳腺癌死亡。值得注意的是，下降速度已从 1998 年至 2011 年的年均下降 1.9% 放缓至 2011 年至 2017 年的 1.3%，这主要是受白人女性趋势的推动。因此，自 2011 年以来，乳腺癌死亡率的黑白差异在过去 3 年扩大后一直保持稳定。尽管如此，尽管发病率较低（126.7 对 130.8），但黑人的死亡率仍然高出 40%（每 10 万人 28.4 对 20.3 人死亡）；这种差异在 50 岁以下的黑人女性中被放大，她们的死亡率是白人的两倍。在最近的 5 年期间（2013-2017 年），西班牙裔（每年 2.1%）、黑人（1.5%）、白人（1.0%）和亚裔/太平洋岛民（0.8%）的死亡率有所下降，但在美洲印第安人/阿拉斯加原住民中稳定。然而，按州划分，内布拉斯加州的乳腺癌死亡率总体上不再下降；在科罗拉多州和威斯康星州的黑人女性；在内布拉斯加州、德克萨斯州和弗吉尼亚州的白人女性中。2016 年至 2017 年期间，在南部四个州和中西部两个州的黑人和犹他州的白人中，乳腺癌是女性癌症死亡的主要原因（超过肺癌）。
