The US National Cancer Institute is taking a hard look at the effects of vitamin C on the body, particularly its alleged ability to treat cancer.
Included in the reports and a three day symposium are the joint reports of Nobel prize winner Linus Pauling and National Cancer Institute director Samuel Broder on uses of asorbic acid in the treatment of malignancies. Pauling, who first advocated the use of vitamin C to cure the common cold, went on to applaud its use in cancer therapy. Although two controlled clinical trials sponsored by the cancer institute has concluded the vitamin was ineffective in advanced cases of cancer, the institute found numerous epidemiological studies that were more optimistic. Of 46 studies, 33 showed evidence of statistically significant protection in cancers of the mouth, oesophagus, stomach, pancreas, breast, anus, colon and cervix.
