Occupational exposure and incidence of female breast cancer at different stages in Taiwan.
Employment status was associated with higher overall hazard of breast cancer diagnosis.
Occupational exposure and incidence of female breast cancer at different stages in Taiwan.
This retrospective cohort study aimed to investigate the associations between the incidence of female breast cancer (female breast cancer) at different stages in various occupations among Taiwanese workers.
We established employed and unemployed cohorts by linking the National Labor Insurance, National Pension Insurance, and Taiwan Cancer Registry databases, including 4,742,717 employed women and 2,124,616 women outside the paid workforce during 2010-2018.
employed women had a higher hazard of breast cancer than unemployed women
Female workers employed in the real estate industry exhibited a higher observed hazard of overall breast cancer (1.10, 1.01-1.20) than those employed in the education industry, whereas a similar trend was observed in the financial and insurance industry (1.07, 1.00-1.13).
Higher observed hazards were also identified for several special occupational health hazard categories, although these estimates should be interpreted cautiously because of the limited precision of some estimates.
This study observed differences in stage-specific female breast cancer incidence between employed and unemployed populations, as well as across various industries and special occupational health hazard categories.
