Within the TriNetX network, BC incidence proportion among women aged 18-40 demonstrated an upward trend from 2014 to 2023, particularly among non-Hispanic White women 30-39 years old. An uptrend was also seen in young AI/AN, Asian, NHPI, and Hispanic women. In addition, increased documented mortality and LR were also observed. These findings underscore the importance of further research to understand these trends and develop diagnostic and therapeutic approaches tailored to younger patients.
