Additional retrospective surveys of deaths among members of the railroad lodges of the international union, together with the cohort study, identified a total of 42 mesotheliomas, two endotheliomas of the pleura, and two cancers of the pleura among former railroad machinists
.Among the machinists employed in other industries, 16 mesotheliomas and six cancers of the pleura were identified.
For decades, machinists, by the nature of their craft, have had a high risk of occupation-related cancer due to asbestos exposure.
