How does aflatoxin cause cancer?

Aflatoxin B1, a genotoxic liver cancer that may cause cancer Genetic changes in target hepatocytes by induction of DNA adducts. AFB1 is metabolized by cytochrome-P450 enzymes to the active intermediate AFB1-8,9 epoxide (AFBO), which binds to hepatocyte DNA to produce DNA adducts.
