Indeed, although mutations may also occur at later stages in carcinogenesis, they represent a necessary first step for the action of many carcinogens, in particular, if occurring in proto-oncogenes and/or tumor suppressor genes. However, UN GHS allows each jurisdiction to choose their concentration limits for germ cell mutagenicity or carcinogenicity: 0.1% or 1%.
