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.

Criteria for Article Selection. 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. Studies examining only plasma levels of dietary antioxidants were excluded.

Added text to state that in a prospective study that explored the association between supplement use and breast cancer outcomes, the use of any antioxidant supplement before and during treatment–including coenzyme Q 10, vitamin A, vitamin C, vitamin E, and carotenoids–was associated with a trend showing an increased hazard of recurrence (cited Ambrosone et al. 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.

late-stage cancer'. vast number of nutritional intervention trials using the antioxidants β-carotene, vitamin A, vitamin C, vitamin E and selenium have shown no obvious effectiveness in preventing gastrointestinal cancer.[13]. Reactive oxygen species (ROS) play important roles in tissue homeostasis, cellular signaling, differentiation, and survival. In this review, we discuss the types of ROS, their impact on cellular processes, and their pro- and antitumorigenic effects.

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. 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 Criteria for Article Selection. 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.

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.

Men kan tillskott av antioxidanter istället vara farligt för hälsan? Ja, antagligen. En ny studie på möss visar att de som fick tillskott av antioxidanter – bland annat E-vitamin – fick dramatiskt förvärrad lungcancer: GP: Antioxidanter kan förvärra cancer. Naturligtvis kan man invända att möss inte är människor.

Reactive oxygen species (ROS) play important roles in tissue homeostasis, cellular signaling, differentiation, and survival. In this review, we discuss the types of ROS, their impact on cellular processes, and their pro- and antitumorigenic effects. Further, we discuss recent advances in our understanding of both endogenous and exogenous antioxidants in tumorigenic processes.
