By moving between geographic regions with differing levels of breast cancer risk, migrant populations of women provide a unique opportunity to examine the impact of exposure to new environments and lifestyles on breast cancer risk.
To address these questions, we determined the breast cancer mortality rates for women from both lower and higher risk countries who had immigrated to Australia and Canada and compared these rates with those exhibited by the population in the origin country and by the destination native-born population.
Individual mortality records covering the years 1984 through 1988 and 1986 census data for Australia and Canada were obtained.
Direct age-standardized mortality rates and rate ratios were calculated for immigrant groups in Australia and Canada.
Age-standardized rate ratios by length of residence in Australia were calculated.
Weighted regression analyses of observed and expected mortality changes were performed.
Breast cancer mortality rates among women in the majority of immigrant groups shifted from the rate observed in their country of origin toward the rate of the native-born population in the destination country. [J Natl Cancer Inst 87 : 1154-1161,1995].
