The notion of cancer prevention through antioxidant intervention arises from the fact that fruits and vegetables contain antioxidants and are linked to low cancer rates in those who consume them. Protection against DNA damage by plant food products can be demonstrated in vitro.

Antioxidants maintain redox homeostasis and prevent ROS-/RNS-induced damages that have been associated with cancer development. In the body, antioxidant defence systems include endogenous (enzymatic and non-enzymatic antioxidants) and exogenous antioxidants supplied by plant foods.

New animal studies explain why supposedly healthy supplements like beta-carotene could exacerbate a dread disease Antioxidant supplementation during radiation therapy poses a conundrum for the radiation oncologist, as antioxidants that protect normal cells from reactive oxygen species may provide the same benefits to cancer cells and reduce the efficacy of treatment. Cancer Epidemiol Biomarkers Prev 13:1276–1282 PubMed Google Scholar Dumont M, Wille E, Stack C, Calingasan NY, Beal MF, Lin MT (2009) Reduction of oxidative stress, amyloid deposition, and memory deficit by manganese superoxide dismutase overexpression in a transgenic mouse model of Alzheimer’s disease. Antioxidants act as electron donors that neutralize reactive oxygen species (ROS) and other free radicals that may otherwise damage DNA and promote tumorigenesis ( 1 ). Consequently, popular wisdom—supported by numerous cellular and preclinical studies—holds that antioxidants protect against cancer ( 2 – 4 ). Pubmed, Google Scholar and (CIs) that described the effect of antioxidants vs placebo on cancer incidence and cancer mortality.

Protection against DNA damage by plant food products can be demonstrated in vitro. Dietary antioxidants and the aetiology of pancreatic cancer: a cohort study using data from food diaries and biomarkers. Banim PJ(1), Luben R, McTaggart A, Welch A, Wareham N, Khaw KT, Hart AR. Author information: (1)Department of Medicine, University of East Anglia, Norwich, UK. 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. The notion of cancer prevention through antioxidant intervention arises from the fact that fruits and vegetables contain antioxidants and are linked to low cancer rates in those who consume them.

Antioxidants maintain redox homeostasis and prevent ROS-/RNS-induced damages that have been associated with cancer development. In the body, antioxidant defence systems include endogenous (enzymatic and non-enzymatic antioxidants) and exogenous antioxidants supplied by plant foods.

National Center for Biotechnology Information total antioxidant status (measured by total radical antioxidant parameter) declines during cancer treatment. Adequately powered trials or observational studies among patients with a specific cancer A study that more directly addresses the issue of antioxidant use concurrently with cytotoxics is that of Lesperance, et al. 24 In this trial, 90 patients with early stage breast cancer who were prescribed megadoses of combination vitamins, minerals, and other antioxidants concurrent with standard therapy were compared with 180 well‐matched controls.
