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,

Sialic Acid as a Biomarker Studied in Breast Cancer Cell Lines In Vitro Using Fluorescent https://pubmed.ncbi.nlm.nih.gov/33837649/ active metal centers are very promising small molecules to be utilized as part of antioxidant therapies.

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. RESULTS: Twelve eligible trials, 9 of high methodological Antioxidants (ISSN 2076-3921; CODEN: ANTIGE) is an international, peer-reviewed, open access journal published monthly online by MDPI.The International Coenzyme Q10 Association (ICQ10A) and Israel Society for Oxygen and Free Radical Research (ISOFRR) are affiliated with Antioxidants and their members receive discounts on the article process charges. The notion that dietary antioxidants can help fight cancer is popular.

as reference 7). In this study, 20% of patients regularly used ≥1 type of antioxidant postdiagnosis. Although cancer survivors often use antioxidants hoping to lessen the toxic effects of chemotherapy and radiation therapy , whether antioxidant use is beneficial for breast cancer survivors is still unclear (14, 15, 33, 34). Jun 13, 2014 Antioxidants and a large number of natural supplements were introduced in Cancer Inst. 88, 1560–1570 10.1093/jnci/88.21.1560 [PubMed] Abstract. Various antioxidants in foods, such as phenolic compounds and carotenoids, were proven to have anticarcinogenic activity. In the case of carotenoids, Dec 29, 2014 Some chemotherapeutic agents and radiation therapy generate reactive oxygen species (ROS), which diminish the cellular antioxidant There is a concern that antioxidants might reduce oxidizing free radicals created by radiotherapy and some forms of chemotherapy, and thereby decrease the Methods: We searched Medline (PubMed), Excerpta Medica database, and the Cochrane Review in October 2007.

Cancer treatment by radiation and anticancer drugs reduces inherent antioxidants and induces oxidative stress, which increases with disease progression. Vitamins E and C have been shown to ameliorate adverse side effects associated with free radical damage to normal cells in cancer therapy, such as mucositis and fibrosis, and to reduce the recurrence of breast cancer.
