Substantial Scientific Flaws of Using Animals in Cancer Research, Part 3 

With respect to how we judge the toxicity of potential biologic activity of a given compound, animal tests are not necessarily the final word. They're probably misleading. High doses of a particular compound given over a period of time may suggest carcinogenicity not so much from their innate carcinogenicity but the fact that they have caused so much tissue damage and tissue [proliferation] that the risk of cancer increases.

- Clark Heath, the vice president for epidemiology and surveillance research at the American Cancer Society

In other words, the way the compounds are administered in animal tests may increase the animals' risk of cancer.
