Occupational exposure and regional variation of malignant mesothelioma in Norway, 1970–79

摘要: This investigation is based on a study of 117 men and 24 women with malignant mesothelioma registered by the Cancer Registry Norway, 1970-79. The age-adjusted incidence rate in for each county varied from 1.7 to 13.3 per million year. Eighty-two percent revealed possible occupational asbestos exposure.
