Breast cancer incidence on the rise among younger women

Breast cancer incidence rates have risen over the past two decades among younger women, a study published January 26 in JAMA Network Open found. Researchers led by Adetunji Toriola, MD, PhD,  from Washington University in St. Louis found higher incidence rates among non-Hispanic Black women ages 20 to 29 and 30 to 39. They also found higher incidence rates for estrogen receptor (ER)-positive, stage I, and stage IV tumors. “Our findings underscore the need for further research into specific breast cancer risk factors among younger women and possible targeted breast cancer prevention strategies for at-risk groups,”  Toriola and colleagues wrote. Breast cancer in young women has a less favorable prognosis compared with older women, with cancers in younger women more likely to have aggressive biological features. Furthermore, women younger than 40 are not recommended for regular screening mammography. The researchers also noted a lack of comprehensive data on recent trends and how period and cohort effects may affect these trends among young women. Toriola and co-authors investigated breast cancer incidence among young U.S. women (ages 20 to 49) with data collected between 2000 and 2019 from 17 registries as part of the Surveillance, Epidemiology, and End Results (SEER) program. They studied the data by patient race and ethnicity, hormone receptor status, tumor stage, and age at diagnosis, as well as how period and cohort effects may affect these trends. The team in...
