Trends in breast cancer mortality by stage at diagnosis among young women in the United States.

ABSTRACT:

Background

Assessing trends in breast cancer survival among young women who are largely unaffected by breast cancer screening will provide important information regarding improvements in the effectiveness of cancer care for breast cancer in the last few decades.

Methods

The cohort for this study consisted of women who were diagnosed with breast cancer between ages 20 and 39 years from the Surveillance, Epidemiology, and End Results program's 9-registry areas from 1975 to 2015. Trends in the breast cancer incidence rate and survival were assessed among young women.

Results

Among women aged 20 to 39 years, breast cancer incidence increased from 24.6 per 100,000 in 1975 to 31.7 per 100,000 in 2015 (annual percent change, 0.5; 95% confidence interval [CI], 0.4-0.6). Among
