Trends in Breast Cancer Rates Among Asian American, Native Hawaiian, and Pacific Islander Women from 2000 to 2022
Background
Breast cancer incidence rates have historically varied among different racial and ethnic groups in the US, with lower rates in Asian American women and higher rates in Native Hawaiian and Pacific Islander women. Recent data suggest a concerning upward trend in breast cancer rates among these populations, particularly among younger cohorts and for aggressive cancer subtypes.
Data Highlights
No numerical data table provided in the source material.
Key Findings
Asian American, Native Hawaiian, and Pacific Islander women experienced the steepest rise in breast cancer incidence among all US racial and ethnic groups from 2017 to 2021 at 3.3% per year.
From 1990 to 2014, annual percentage change (APC) in breast cancer incidence varied significantly among Asian American groups, with increases ranging from 0.65% in Chinese to 2.55% in Korean females.
Women aged 65 years or older in these populations saw the fastest increase in triple-negative breast cancer incidence at 5.5% from 2016 to 2019.
Incidence rates for breast cancer in women under 50 years increased by 4.0% annually from 2016 to 2019.
ERBB2-positive breast cancers are more prevalent among Asian American, Native Hawaiian, and Pacific Islander women compared to other racial and ethnic groups.
There has been a notable increase in distant-stage breast cancer among these populations, indicating that rising incidence trends are not solely due to increased screening.
Clinical Implications
Healthcare providers should be aware of the rising breast cancer incidence rates among Asian American, Native Hawaiian, and Pacific Islander women, particularly in younger age groups. This necessitates tailored screening and prevention strategies to address the unique needs of these populations.
Conclusion
The increasing trends in breast cancer incidence among Asian American, Native Hawaiian, and Pacific Islander women highlight the need for ongoing surveillance and targeted research to understand the underlying factors driving these changes.
