Abstract
The mechanism of chemical carcinogenesis has been explained by either a two-stage theory or a multi-stage theory which consists of initiation, promotion and progression stages.1 In these stages, the promotion stage is long-term and reversible reaction, and the development of anti-tumor-promoters has been regarded as the most effective method for the chemoprevention of cancer.
