title: Possible enhancement of carcinogenesis by selenium in an animal tumor model.
abstract: Findings from animal tumor models and epidemiologic investigations of humans have identified selenium as a possible anticarcinogenic nutrient. Recent evidence, however, indicates that under some circumstances high levels of selenium can actually enhance experimental tumorigenesis.
