Study Finds Antioxidants Doubled Spread of Skin Cancer in Mice

THURSDAY, October 8, 2015 (The Wall Street Journal) — A new study has shown antioxidants doubled the spread of melanoma in mice—adding fresh evidence that taking antioxidant vitamin supplements may fuel the growth of cancer cells.

Researchers at the Sahlgrenska Academy in Gothenburg have found that the antioxidant N-acetylcysteine or NAC, which is available in some nutritional supplements, doubled the rate at which malignant melanoma–the most serious form of skin cancer–spread to the lymph nodes of mice. Repeating the experiment in human cells grown in lab cups, the scientists found that cancerous skin cells inserted with NAC and vitamin E, another strong antioxidant, became better at invading adjacent tissue.
