Some trials show that antioxidants actually increase cancer risk and a study in mice showed that antioxidants accelerate the progression of primary lung tumors. However, little is known about the impact of antioxidant supplementation on the progression of other types of cancer, including malignant melanoma.

2014-01-29 · Normal doses of vitamin E and smaller doses of the antioxidant supplement acetylcysteine increased the growth of tumors in mice with early lung cancer, the researchers reported in the Jan. 29 issue In 2014, Bergo’s group gave NAC to mice with lung cancer. Compared to control mice, the dosed mice developed larger tumors and they died sooner. The team showed that antioxidants reduced potentially damaging reactive oxygen species in tumor cells and reduced the activity of a tumor suppressor called p53.

People who smoke or have lung cancer should think twice about taking vitamin supplements, according to a Swedish study Wednesday that showed certain antioxidants may make tumors grow faster. 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.
