be carcinogenic
Carcinogenesis is cancer. There are probably four causes of cancer: chemical factors, physical factors, viruses and family inheritance.
Many chemicals have definite or suspected carcinogenic effects on animals, some of which may be related to human cancer. Most chemicals need to be metabolized and activated in the body (mainly in the liver) to cause cancer, which is called indirect carcinogen. A few chemicals can cause cancer without metabolic transformation in the body, which is called direct carcinogen.
