Kreftrisiko blant norske papir- og cellulosearbeidere

Abstract

Kreftregisteret, Institute of population-based cancer researchTelefonResults from a historical prospective cohort study on Norwegian pulp and paper workers showed a significant increase in risk of lung cancer, pleural mesothelioma, colon cancer and malignant melanomas among men, compared to the Norwegian population. The risk of lung cancer was highest among sulphite mill workers. The risk of pleural mesothelioma was highest among maintenance workers with asbestos exposure. Most of the increased risk in lung cancer can be explained by a combination of smoking habits and asbestos use, although an effect of other work-related exposures (sulfur and chloride compounds, wood dust) cannot be excluded. Among the female part of the cohort we found a significant excess in risk of ovarian cancer. The risk was highest among those younger than 55 years, and mostly among those working in paper departments. Relatively little is known about the causes of ovarian cancer, but it is however known that 5-7% can be explained by hereditary factors. Furthermore, fertility pattern plays a role. Asbestos and talc, which both have been used in the pulp and paper industry, are occupational and environmental agents, discussed as possible carcinogens for ovarian cancer.
