Cancer morbidity in Swedish shipyard workers 1978-1983.

The cancer morbidity in 3787 shipyard workers was studied between 1978 and 1983. In these shipyards the use of asbestos was abandoned in 1972. The overall cancer morbidity was found to be similar to that of the male population of the same city, but there were four cases of mesothelioma. There were 11 cases of lung cancer, as opposed to 9.8 expected cases. Men with both heavy and long exposure to asbestos had no increased risk of lung cancer. The occurrence of pleural plaques was not associated with the risk of developing cancer.
