According to the abstract of study of "Vitamin C and cancer: what can we conclude--1,609 patients and 33 years later?" by Cabanillas F., posted in US National Library of Medicine National Institutes of Health, researcher concluded that that we still do not know whether Vitamin C has any clinically significant antitumor activity. Nor do we know which histological types of cancers, if any, are susceptible to this agent. Finally, we don't know what the recommended dose of Vitamin C is, if there is indeed such a dose, that can produce an anti-tumor response.
