**2.3 Aflatoxin**

Consumption of foods contaminated with aflatoxins produced by fungi can lead to the formation of HCC [8, 27, 28]. Aflatoxin B1, one of the toxin types, is thought to be mainly responsible for HCC formation [8]. It contributes to the formation of HCC by making mutations (Guanin and Thymine mutations) in DNA via cytochrome p450. Aflatoxin exposure is thought to affect patients with chronic HCV hepatitis more [8, 29, 30].
