  • Descrição: Background Surveillance, Epidemiology, and End Results (SEER) data from 1973‐2010 have been used to show that minority women have disproportionately higher percentages of breast cancers diagnosed at younger ages in comparison with White women. Methods The authors analyzed SEER 21 invasive breast cancer incidence data for 2014‐2017 and National Center for Health Statistics mortality data for 2014‐2018 and compared invasive incidence and mortality by age in non‐Hispanic Black (NH‐Black), Asian American/Pacific Islander (AAPI), Native American, and Hispanic women with those in non‐Hispanic White (NH‐White) women. They evaluated incidence rates and percentages of invasive breast cancer cases and breast cancer deaths occurring before the age of 50 years along with advanced‐stage incidence rates and percentages in minority women versus NH‐White women. Results Recent SEER data showed that invasive breast cancers were diagnosed at significantly younger ages in minority women versus NH‐White women. Among women diagnosed with invasive breast cancer, compared with NH‐White women, minority women were 72% more likely to be diagnosed under the age of 50 years (relative risk [RR], 1.72; 95% confidence interval [CI], 1.70‐1.75), 58% more likely to be diagnosed with advanced‐stage breast cancer under the age of 50 years (RR, 1.58; 95% CI, 1.55‐1.61), and 24% more likely to be diagnosed with advanced‐stage (regional or distant) breast cancer at all ages (RR, 1.24; 95% CI, 1.23‐1.25). Among women dying of breast cancer, minority women were 127% more likely to die under the age of 50 years than NH‐White women. Conclusions NH‐Black, AAPI, Native American, and Hispanic women have higher proportions of invasive breast cancers at younger ages and at advanced stages and breast cancer deaths at younger ages than NH‐White women. Lay Summary This study analyzes the most recently available data on invasive breast cancers and breast cancer deaths in US women by age and race/ethnicity. Its findings show that non‐Hispanic Black, Asian American/Pacific Islander, Native American, and Hispanic women have a higher percentage of invasive breast cancers at younger ages and at more advanced stages and a higher percentage of breast cancer deaths at younger ages than non‐Hispanic White women. The latest Surveillance, Epidemiology, and End Results incidence data show that, among women diagnosed with invasive breast cancer, non‐Hispanic Black, Asian American/Pacific Islander, Native American, and Hispanic women have higher relative risks of being diagnosed before the age of 50 years and of being diagnosed with advanced‐stage breast cancer in comparison with non‐Hispanic White women. The latest National Center for Health Statistics mortality data show that, among women dying of breast cancer, women of each minority have a higher relative risk of dying under the age of 50 years than non‐Hispanic White women.
