Inter- and intra-ethnic differences for female breast carcinoma incidence in the continental United States and in the state of Hawaii.
Ethnic diversity is well-documented for female breast carcinoma incidence in the continental US but is not so well-established in the state of Hawaii. ⋯ We observed inter- and intra-ethnic differences for female breast carcinoma in the continental US and in the state of Hawaii. While inter-racial disparities were expected, intra-racial differences were somewhat unexpected and possibly due to variations in racial subgroup mixing and/or cultural assimilation. For example, API women with breast carcinoma in the continental US included 96.03% Asians and 2.4% Pacific Islanders. In contrast, API women with breast carcinoma in Hawaii included 76.52% Asians and 23.46% Pacific Islanders. Moreover, APIs were more likely to be first-generation migrants in the continental US ( approximately 92%) than in Hawaii ( approximately 34%). Future studies should attempt to disaggregate racial data to separately characterize epidemiological patterns for individual ethnic groups.
