Vitamin C Injection May Treat Cancer

Aug 06, 2008
New study shows that vitamin C injections have the potential to treat cancer, by reducing the size of a tumor.

The researchers who conducted the new study on mice discovered an unexpected effect of vitamin C, promising its use as a drug for cancer treatment.

Dr. Mark Levine,a co-author of the study and chief of the U.S. National Institutes of Health's Molecular and Clinical Nutrition Section said that the findings are to be confirmed in humans. Scientists also need further research to find out against what type of cancer this might be effective.

Vitamin C is known to be a highly effective antioxidant that is used in treatment of such conditions as cold and heart disease. Now this vitamin shows promise for fighting cancer.

Researchers used intravenous doses of vitamin C in the study to increase the level of vitamin C. The injection can evade the digestive system blockage that allows only certain amount of this vitamin. The injections of vitamin C produced hydrogen peroxide, which led to reduction of tumors in the mice by 43 to 51 percent. The mice used in the study had ovarian, pancreatic and brain cancer.

It is still unknown why certain types of cancer are immune to treatment and normal cells remain safe during therapy, scientists say.

However, it is too soon to say that vitamin C injections will work even if the findings show their effectiveness on humans. The vitamin C is likely to be used as a part of the treatment of cancer if the further research will be proven.

The study appeared in the August issue of the Proceedings of the National Academy of Sciences.
