A study by Swedish researchers reported recently in Science Translational Medicine shows that two antioxidants— N -acetylcysteine and vitamin E—accelerate the progression of early lung tumors in mice and in human lung cancer cell lines.
In some preclinical studies, antioxidants have been found to promote tumor growth and metastasis in tumor-bearing mice and to increase the ability of circulating tumor cells to metastasize (29–31). Until more is known about the effects of antioxidant supplements in cancer patients, these supplements should be used with caution. Därför kan antioxidanter förvärra cancer. Publicerad: 3 Februari 2014, 09:11. Forskare i Göteborg har hittat en mekanism som gör att antioxidanter kan påskynda utvecklingen av lungcancer.

Bergo1,3† Antioxidants in the diet and supplements are widely used to protect against cancer, but clin ical trials with 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. In a previous study on mice, Swedish researchers said antioxidants, including vitamin E, caused a three-fold increase in the number of cancer tumours and led the rodents to die twice as fast.
Antioxidants were administered 1 week after the induction of lung cancer, and mice were euthanized 8 to 10 weeks later. For Antioxidants made lung cancer worse In a study from 2014, Bergö and colleagues picked up where the previous research had left off and tested specifically how lung tumours in mice would react to the two antioxidants N-acetylcysteine (NAC) and vitamin E. The results were troubling.
Cancer cells produce high levels of mitochondria-associated reactive oxygen species (ROS) that can damage macromolecules, but also promote cell signaling and proliferation. Therefore, mitochondria-targeted antioxidants have been suggested to be useful in anti-cancer therapy, but no studies have convincingly addressed this question. Here, we administered the mitochondria-targeted antioxidants
