Incidence of cancer among Norwegian boiler welders.
Objectives-The cancer incidence among 2957 boiler welders was investigated.
The subjects were registered electrical welders from 1942 to 1981.
A subcohort of 606 stainless steel welders was studied separately.
Methods-The investigation was a historical prospective cohort study based on a national registry.
The loss of follow up was 4.9%. Results-There were 625 deaths (659 expected).
There were 269 cancer cases (264 expected).
An excess of lung cancer was found ; 50 cases v 37.5 expected.
There were three cases of pleural mesotheliomas v 1.1 expected.
The subcohort of stainless steel welders had six cases of lung cancer v 5.8 expected, and one case of pleural mesothelioma v 0.2 expected.
Conclusions-The welders in the study were assumed to represent a qualified work force.
These welders had a small excess risk of lung cancer.
The excess risk did not seem to be associated with stainless steel welding.
Smoking and asbestos exposure were potential confounders.
