Introduction:
This study examined recent trends and outcomes in breast cancer among Black women under age forty.
Methods:
Breast cancer incidence data from the National Cancer Database (2010-2022) were analyzed using U.S. Census data population estimates.
Results:
Among 188,311 women under forty, 16.4 % were Black, compared to 11.3 % in older Black women. From 2010 to 2022, incidence in young Black women rose 5.3 %, compared to 19.9 % in White, 27.7 % in Hispanic, and 18.9 % in Asian/Pacific Islander women. Triple-negative breast cancer was more common in young Black women (16.3 %) vs. young Non-Black women (12.1 %). Black women under forty had 50 % higher odds of death (OR 1.50; 95 % CI: 1.46-1.55, p < .0001) compared to their Non-Black peers after adjusting for age, tumor characteristics, and treatment.
Conclusions:
Young Black women have more aggressive breast cancers and worse overall survival than Non-Black young women, though incidence has remained stable over the past decade.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
