CAS No.: 7782-49-2
5. Summary of Data Reported and Evaluation
5.1 Animal carcinogenicity data
Selenium compounds were tested in mice and rats by the oral route.
Although in one experiment in rats selenium produced an increase in
the incidence of liver tumours, the available data are insufficient to
allow an evaluation of the carcinogenicity of selenium compounds.
5.2 Human carcinogenicity data
The available data provide no suggestion that selenium is carcinogenic
in man, and the evidence for a negative correlation between regional
cancer death rates and selenium is not convincing.
Subsequent evaluation: Suppl. 7 (1987) (p. 71: Group 3)
For definition of Groups, see Preamble Evaluation.
