Risks for respiratory and gastric cancer in wood-working occupations in Denmark.
Cases of cancer notified to the Danish Cancer Registry during the period 1970 to 1984 in the age groups 16 to 66 years have been linked to information on employment kept on file in the nationwide Supplementary Pension Fund since 1964. Industrial hygienists classified industrial groups as defined by the Pension Fund with regard to exposure to wood dust, and a list of industries with major exposure to wood dust was defined. The risk for cancer of the respiratory system and the gastrointestinal tract was evaluated by means of a proportional cancer incidence analysis. A fourfold increase in risk for sinonasal cancer was found among men involved in the manufacture of wooden furniture, and a twofold increase in risk for gastric cancer was seen in all of the component industries of basic wood-processing. In contrast, no excess of gastric cancer could be detected in men working in the manufacture of wooden building materials and wooden furniture, and a risk below unity was seen for those in carpentry and joinery. The elevated risk for gastric cancer in some wood-processing industries is probably due to social factors also common to men in agriculture and manufacturing. The absence of an increased risk for gastric cancer in trades in which a high risk for sinonasal cancer is seen indicates that wood dust is not of aetiological importance for gastric cancer. No excess of total lung cancer or of the adenocarcinoma subtype was seen in any of the wood-processing industries.
