3.1
carcinogen
substance or mixture that may cause cancer or increase the incidence of cancer. Substances and mixtures that induce benign and malignant tumors in good experimental studies on animals are also considered as assumed or probable human carcinogens, unless there is conclusive evidence that the tumor formation mechanism has nothing to do with humans. The classification of substances or mixtures according to their carcinogenic hazards is based on their properties, and no information on the potential carcinogenic risk for human beings in using them is provided
