Exposure6
A case-control analysis of lung cancer did not show any association with exposure to cadmium. (inchem.org)
Excess mortality from lung cancer was reported among workers employed in a US cadmium recovery plant, and a dose-response relationship was demonstrated between estimated cumulative exposure to cadmium and lung cancer risk. (inchem.org)
In a large cohort of workers from 17 cadmium processing plants in the United Kingdom, decreased mortality from prostatic cancer was observed, while that from lung cancer was increased in the overall cohort and there were suggested trends with duration of employment and with intensity of exposure.

The increase in lung cancer risk was stronger in the small proportion of workers with high cadmium exposure. (inchem.org)
Excess mortality from stomach cancer, which was not related to intensity of cadmium exposure, was also reported among these workers. (inchem.org)
Constraints that influence the assessment of both lung and prostatic cancer risk are that the number of long-term, highly exposed workers is small, the historical data on exposure to cadmium are limited, particularly for the non-US plants, and the ability to define and examine a gradient of cumulative exposure varies across studies.
