Abstract

The relationship between shipbuilding and related industries and risk of fatal lung cancer (1960–1975) is described for selected Louisiana parishes. Deaths from lung cancer were matched to deaths not caused by cancer. Shipbuilders had a significantly increased risk (greater than twofold) of dying of lung cancer as compared with other causes. The risk of dying of lung cancer in related occupations (seamen and longshoremen) was also increased. Information on laterality of lung cancer was not supportive of particulate substances contributing to causality due to the large number of unspecified cases. The preponderance of deaths appears to be occurring in men with a greater number of years of exposure to this industry and in those aged 20 to 34 years in 1940. These common occupations in Louisiana could contribute to the high rate of lung cancer.
