Dorgan JF, Ziegler RG et al (1993) Race and sex differences in associations of vegetables, fruits, and carotenoids with lung cancer risk in New Jersey (United States). 2021-04-06 2015-10-07 Antioxidants (irrespective of type) versus placebo did not significantly affect the incidence of gastrointestinal cancers (0·96, 0·88–1·04, fixed; 0·90, 0·77–1·05, random; figure 2). 1129 (1·4%) of 78 280 participants in the antioxidant group compared with 978 (1·6%) of 62 312 in the placebo group developed gastrointestinal cancer. 2014-02-27 This review focuses on the roles antioxidants and pro-oxidants in colorectal cancer (CRC). Considerable evidence suggests that environmental factors play key roles in the incidence of sporadic CRC. If pro-oxidant factors play an etiological role in CRC it is reasonable to expect causal interconnections between the well-characterized risk factors for CRC, oxidative stress and genotoxicity.

Antioxidants are widely used to protect cells from damage induced by reactive oxygen species (ROS). The concept that antioxidants can help fight cancer is deeply rooted in the general population,

Fasano A. Leaky Antioxidants accelerate lung cancer progression in mice.

The objective of this review is to provide information about the effects of antioxidants during oncology treatments and to discuss the possible events and efficacy. Much debate has arisen about whether antioxidant supplementation alters the efficacy of cancer chemotherapy. The roles and functions of antioxidant micronutrients, such as vitamin C (ascorbate), vitamin E (alpha-tocopherol), selenium, and vitamin A, provided through diet for the prevention of cancer are discussed in the present work. Various dietary antioxidants have shown considerable promise as effective agents for cancer prevention by reducing oxidative stress which has been implicated in the development of many diseases, including cancer.
