Carcinogen metabolism and individual susceptibility.
Many chemical carcinogens need activation by drug metabolizing enzymes principally cytochrome P450 enzymes to become capable of binding to deoxyribonucleic acid and initiating the carcinogenic process. The activity and inducibility of drug metabolizing enzymes are regulated by interplay between genetic host and environmental factors.
