It had long been hypothesized that antioxidants might be able to protect against cancer because they neutralize reactive oxygen species (ROS) that can damage DNA. In laboratory and animal studies, the presence of increased levels of exogenous antioxidants has been shown to prevent the types of free radical damage that have been associated with cancer development.

Human trials conducted in the 1980s and 1990s found that the antioxidants beta-carotene, vitamin A and vitamin E substantially increased the incidence of lung cancer in smokers, he said. Oxidative DNA damage is a known risk factor of cancer. Antioxidants, such as quercetin, are thought to play an important role in protecting cells from oxidative stress induced by reactive oxygen species (ROS). ROS and RNS (reactive nitrogen species) play a vital role in development of Cancer in Human.

Dietary intake of antioxidants may confer a range of benefits, including potential protective effects against skin cancers. Coupled with UV avoidance and appropriate use of sunscreens, antioxidant consumption may help reduce an individual’s risk for developing skin cancer, especially SCC or BCC. 1. 2014-01-29
Human Papillomavirus is a well-known risk factor for cervical cancer, which is the fourth most common female cancer and contributed to 7.5% of cancer deaths for women worldwide in 2018. Certain HPV strains are more likely to trigger precursor events leading to cancer development.

INTRODUCTION Despite discouraging results from randomized trials,1-3 there remains an interest in antioxidant nutrients and cancer risk. It has been observed that antioxidants reduce oxidative DNA damage and genetic mutations,4-6 and they may protect There is growing interest in natural antioxidants and their potential effects on breast cancer (BC). Epidemiological evidence, however, is inconsistent. We prospectively evaluated the association between dietary intake of vitamins A, C, and E, selenium, and zinc and BC among 9983 female participants from the SUN Project, a Mediterranean cohort of university graduates. Because it is biologically plausible that antioxidants interact with genetic variation in antioxidant defense and repair of oxidative DNA damage, the associations between selected polymorphisms and pancreatic cancer risk were stratified by low and high levels of dietary antioxidants (defined as < and ≥ median values of controls, respectively) regardless of whether the interaction terms Antioxidants in the foods we eat can neutralize the unstable molecules, reducing the risk of damage. Peter Close / Istockphoto.com / Stock Photo We will look at the structure, causes, and effects of free radicals, as well as what you should know about antioxidant supplements if you have cancer.

2014-03-18 These findings suggest that dietary iron intake may be associated with an increased breast cancer risk, especially in women who did not received antioxidants during the trial and who consumed more lipids. This supports the experimental results suggesting that breast cancer risk may be increased by iron-induced lipid peroxidation.
