Chemical and physical carcinogenesis: advances and perspectives for the 1990s.

Abstract excerpt

Carcinogenesis is a multistage process driven by carcinogen-induced genetic and epigenetic damage in susceptible cells that gain a selective growth advantage and undergo clonal expansion as the result of activation of protooncogenes and/or inactivation of tumor suppressor genes. Therefore, the mutational spectra of chemical and physical carcinogens in these critical genes are of interest to define endogenous and...
