One of the contributory causes of colon cancer is the negative effect of reactive oxygen species on DNA repair mechanism. Currently, there is a growing support for the concept that oxidative stress may be an important etiological factor for carcinogenesis. The purpose of this review is to elucidate the role of oxidative stress in promoting colorectal carcinogenesis and to highlight the potential protective role of antioxidants. Several studies have documentes the importance of antioxidants in countering oxidative stress and preventing colorectal carcinogenesis. However, there are conflicting data in the literature concerning its proper use in humans, since these studies did not yeld definitive results and were performed mostly in vitro on cell population, or in vivo in experimental animal models.
