【Abstract】 In recent years, several developments have allowed new insights into the effect of microelement on carcinogenic process. These new insights can be concluded as follows:1. The microelement contains the direct carcinogenesis;2. The microelement contains the co—carcinogenesis, e. g;(1) It may be that strengthen and foster the mobilization of chemical carinogen in body.(2) It may be that mobilizes tumor virus.(3) It is generally agreed that produce endocrine imbalance and accelerate carcinogenic process.3. The microelement contains the repressed carcinogenesis.更多还原
