Vitamin C's effects on cancer have been known since the late 1970's when Linus Pauling, PhD and Ewan Cameron, MD, published a case report about 100 terminal cancer patients who had been treated with high dose IV and oral vitamin C. The patients who received this therapy survived an average of 300 days longer than a control group of patients with similar disease status and 22 percent of them lived longer than one year compared to just 0.4% in the control group.
Dr. Mark Levine, MD, a researcher at the National Institute of Health has done a great deal of work on the mechanism of vitamin C in the treatment of cancer. He found that vitamin C interacts with iron and other metals in the extracellular fluid (as opposed to within the cells) to create hydrogen peroxide. Hydrogen peroxide plays a vital signalling role in the immune system, marshalling white blood cells to sites of injury or disease. In high concentration, hydrogen peroxide does much more. It damages the DNA (genes) and mitochondria (energy production factories) of cancer cells, shuts down their energy supply and kills them outright. Best of all — and unlike virtually all conventional chemotherapy ddrugs that destroy cancer cells — it is selectively toxic. No matter how high the concentration, vitamin C does not harm healthy cells.
The body tightly control levels of vitamin C by limiting intestinal absorption. Intravenous administration bypasses this control mechanism and blood levels rise in a dose-dependent manner. For example, 10 grams of vitamin C raises blood levels 25 times higher than the same dose taken orally and this increases 70-fold as doses get larger.
Laboratory studies reveal that this therapy is effective against many types of cancer including lung, brain, colon, breast, pancreatic and ovarian. Animal studies show that when human cancers are grafted into animals, high dose IV vitamin C decreases tumour size by 41 to 53% in diverse cancer types know for both their aggressive growth and limited treatment options.
Many people with cancer also have chronic viral infections (or viral load) which weakened the immune system. IV vitamin C reduces the viral load.
IV vitamin C is not a cure-all for cancer but it appears to have many beneficial effects. IV vitamin C is safe and well tolerated. The ideal treatment schedule is twice a week or more for a very aggressive tumour. Regular infusions are necessary but they may be tapered off as the patient improves.
