Pleural mesothelioma is a rare cancer,· often occurring among workers exposed to asbestos. Environmental airborne asbestos levels in Quebec's asbestos mining areas have been lower than those in asbestos jobs, but higher than in general non-mining towns of Quebec. We compared the incidence of pleural mesothelioma among women living in asbestos mining areas to the incidence in other areas in Quebec. Potential cases of mesothelioma with pathology reports dated 1970 to 1989 were identified from record reviews in some 80 hospitals in 9 sociosanitary regions in Quebec, representing 80% of the female population. Following in-depth pathology and chart reviews for all women with any mention of mesothelioma in the medical file, 131 were classified as possible, probable or definite pleural mesothelioma cases. Incidence rates were computed with census-based population denominators for the study areas, and age adjustment was done using the 1981 Quebec female population. The age-adjusted incidence rate of pleural mesothelioma in mining areas (agglomerations of Thetford Mines and Asbestos) was 23.8 per 1,000,000 women per year [95% confidence interval (CI): 12.7-43.1], as compared to 2.2 per 1,000,000 women per year [95% CI: 1.9-2.6] in the non-mining areas, resulting in an age-adjusted rate ratio of 10.6 [95% CI: 5.3-19.2]. Five (5) of the 12 cases from the mining areas had worked in the asbestos industry, and all but one have lived with an asbestos worker. The apparent excess risk is likely due to exposure of these women to asbestos, either at work or at home.
