Sharp Rise in Breast Cancer Among Asian American Women Stuns Researchers
A new UCSF study finds invasive breast cancer rates climbing rapidly for Asian American women, especially those under 50 and with aggressive tumors.
Researchers at the University of California - San Francisco examined about 150,000 invasive breast cancer diagnoses from 2000 to 2022 using SEER data covering nine Asian American, Native Hawaiian and Pacific Islander groups in 14 states. They discovered an annual rise of more than 3% in nearly every Asian American subgroup, with Chinese and Vietnamese women seeing the highest increases, while Native Hawaiian rates grew about 1% per year.
The most alarming trends involve women under 50 and cases of advanced disease, including triple-negative breast cancer, which rose over 6% each year among Chinese Americans from 2017 to 2022. Senior author Scarlett Lin Gomez emphasized that screening alone cannot account for these jumps, suggesting unidentified risk factors may be at play. Ongoing UCSF projects, the CRANE study and the ASPIRE cohort, aim to uncover these drivers and improve culturally tailored education, screening, and follow-up for affected communities.
Why it matters
The accelerating breast cancer rates signal emerging health disparities that could affect millions of Asian American women if not addressed.
