Cause‐specific mortality and cancer morbidity in 390 male workers exposed to high purity talc, a six‐decade follow‐up

With the clear limitations of a small cohort, our results do hint at an effect of talc dust on mortality from NMRD other than pneumoconiosis, covered by a strong and persisting healthy worker effect. Also, an effect on CVD mortality, masked by a healthy worker selection into the cohort cannot be ruled out. Excess mortality from pneumoconiosis seen in other studies, may reflect exposure to quartz and, possibly, bias due to comparability problems.
