Abstract: Objectives. We estimated trends in breast cancer incidence rates for specificAsian populations in California to determine if disparities exist by immigrantstatus and age.Methods. To calculate rates by ethnicity and immigrant status, we obtaineddata for 1998 through 2004 cancer diagnoses from the California Cancer Registryand imputed immigrant status from Social Security Numbers for the 26% ofcases with missing birthplace information. Population estimates were obtainedfrom the 1990 and 2000 US Censuses.Results. Breast cancer rates were higher among US- than among foreign-bornChinese (incidence rate ratio [IRR]=1.84; 95% confidence interval [CI]=1.72, 1.96)and Filipina women (IRR=1.32; 95% CI=1.20, 1.44), but similar between US- andforeign-born Japanese women. US-born Chinese and Filipina women who wereyounger than 55 years had higher rates than did White women of the same age.Rates increased over time in most groups, as high as 4% per year among foreignbornKorean and US-born Filipina women. From 20002004, the rate among USbornFilipina women exceeded that of White women.Conclusions. These findings challenge the notion that breast cancer rates areuniformly low across Asians and therefore suggest a need for increasedawareness, targeted cancer control, and research to better understand underlyingfactors.
