The untreated animals are maintained on test at the same time as the treated animals and housed under the same conditions in the same laboratory. Because the concurrent controls are thus similar to the exposed animal

Such studies are generally performed in both sexes of two rodent species, typically rats and mice, over a period of about 24 months. Chronic toxicity studies are also carried out in larger laboratory animal species, such as monkeys or dogs. The duration of

Unfortunately, decades of carcinogenicity testing have failed to provide an unequivocal set of guidelines that determines the true carcinogenic potential of a compound in laboratory animals or humans. Furthermore, there is often considerable
