Recent studies have revealed that several cancers appear to benefit from increased levels of antioxidants. Multiple studies in mice show that increased antioxidants accelerate cancer ().In addition, some clinical trials have demonstrated that antioxidant supplements led to higher incidence of lung cancer in smokers ().As a consequence, arguments to decrease antioxidants have been offered as a

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. 2018-03-11 For tumors to progress efficiently, cancer cells must overcome barriers of oxidative stress. Although dietary antioxidant supplementation or activation of endogenous antioxidants by NRF2 reduces oxidative stress and promotes early lung tumor progression, little is known about its effect on lung cancer … Recent studies have revealed that several cancers appear to benefit from increased levels of antioxidants.

A literature search was performed using Pubmed with the medical subheadings diet, antioxidants, and prostaticneoplasms to search for human studies of prostate cancer risk and antioxidants from diet or supplements published until April, 2013.

Further, we discuss recent advances in our understanding of both endogenous and exogenous antioxidants in tumorigenic processes. 2018-07-14 2020-10-14 2014-05-03 2019-08-13 2015-10-07 To investigate how antioxidants might affect cancer progression, Martin Bergö, Ph.D., of the University of Gothenburg in Sweden, led a 2014 study in mouse models of human lung cancer. The researchers found that adding the antioxidants N-acetylcysteine (NAC) or vitamin E to the diet of mice with small lung tumors substantially increased the number, size, and stage of the tumors. 2003-08-01 2007-05-16 Breast cancer is the second most common type of cancer worldwide and the most frequent one among women.

Certain dietary antioxidants such as vitamin E and vitamin C are important for maintaining optimum health. There is now much interest in polyphenolic products of the plant phenylpropanoid pathway as they have considerable antioxidant activity in vitro and are ubiquitous in our diet. Rich sources include tea, wine, fruits and vegetables although levels are affected by species, light, degree of

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. The use of antioxidants during cancer therapy is currently a topic of heated debate because of an overall lack of clear research findings. Some data suggest antioxidants can ameliorate toxic side effects of therapy without affecting treatment efficacy, whereas other data suggest antioxidants interfere with radiotherapy or chemotherapy.

Some studies suggest a favorable role of antioxidants on breast cancer, but this is still controversial.The main objective of this article was to determine the safety and efficacy of antioxidant supplements on breast cancer.In order to gather evidence, main databases (MEDLINE, PubMed 2014-01-29 2004-11-01 The notion that dietary antioxidants can help fight cancer is popular. However, the mechanism(s) behind the effect of antioxidants in cancer is still unclear.

To counterbalance ROS-mediated injury, an endogenous antioxidants defense system exists; how …. The purpose of this review is to survey the literature on modern biological theories of cancer and the roles of dietary antioxidants in cancer. 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. For cancers of the colon, breast, and prostate, the current data do not support a protective effect of antioxidants. More definite conclusions about the benefits of antioxidants in cancer prevention will be derived from on-going intervention trials.
