Cancer is a group of highly complex and heterogeneous diseases with several causes. According to the stochastic model, cancer initiates from mutation in somatic cells, leading to genomic instability and cell transformation. This canonical pathway of carcinogenesis is related to the discovery of important mechanisms that regulate cancer initiation. However, there are few studies describing genetic and metabolic alterations that deregulate transformed cells, resulting in epithelial–mesenchymal transition (EMT) and its most dramatic consequence, the metastasis. This review summarizes the main genetics and metabolic changes induced by reactive oxygen species (ROS) that lead to EMT.
