Background: Cancer refers to a group of diseases that are associated with a disturbance in the control of cell growth and metabolism. Indeed, the unbalanced control of cellular proliferation is a primary characteristic of cancer cells and, as such, any molecule capable of inhibiting cancer cell proliferation may also be useful as a potential chemo-preventive agent. Throughout history, antioxidants have been the most significant source of anticancer and chemopreventing agents. More than 1,000 different phytochemicals are already proved to possess interesting chemopreventing activities. Antioxidants consist of a wide variety of biologically active phytochemicals including phenolics, flavonoids, carotenoids, etc., that have been shown to suppress early and late stages of carcinogenesis. Objective: To review recent biochemical and molecular mechanisms, in relation to natural and synthetic chemopreventing substances (antioxidants) for cancer control and management. Major Findings: Antioxidants exert anticancer effects via a variety of mechanisms, including removal of carcinogenic agents, modulation of cancer cell signaling and cell cycle progression, promotion of apoptosis and modulation of enzymatic activities. Conclusion: This review provides an updated and comprehensive overview on the anticancer effects of antioxidants in-vitro and in-vivo animal models including recent intervention studies. Finally, possible mechanisms of action involving antioxidant and prooxidant activity as well as interference with cellular functions are discussed.
