Common antioxidants such as vitamins A, C, and selenium and zinc when taken additionally can all cause blood vessels in cancer to grow. The discovery has come as a surprise as antioxidants were believed to be protective. The researchers said that natural levels in food were fine but if people take supplements containing antioxidants as well then the extra amount can fuel tumor growth. The study, published in the Journal of Clinical Investigation, was carried out by the Karolinska Institutet in Sweden. It concluded that Vitamin C and other antioxidants stimulate the formation of new blood vessels in lung cancer tumors." They say this could apply to all cancers and the spread of cancer.
