High-dose Vitamin C will promote oxidation when it circulates in very high concentrations in highly oxygenated blood. Healthy cells tolerate high dosages because of catalase, an enzyme that neutralizes oxidation immediately. Catalase is abundant in our blood and normal tissues but generally scant in malignant tumors, this lack in cancerous tissues allows Vitamin C’s oxidative capacity to selectively kill malignant cells. Researchers have found that a highly concentrated vitamin C dose is selectively toxic to cancer cells, meaning the dose harms cancer cells but not healthy tissue. Vitamin C breaks down to generate hydrogen peroxide, which can damage tissue and DNA, tumor cells with low levels of catalase enzyme activity are much less capable of removing hydrogen peroxide than normal cells, and are more susceptible to damage and death when they are exposed to high doses of Vitamin C. High dose Vitamin C is a non-toxic chemotherapeutic and oxidative agent, it is a natural element that works against cancer without harming healthy cells and without the negative side effects of conventional cancer treatments.
Scientific Evidence
The first-ever study in which vitamin C was given to cancer patients was carried out in the 1970s, by Dr. Linus Pauling and Dr. Ewan Cameron, a cancer specialist, working in Scotland. They gave 100 terminally ill cancer patients 10g (10,000mg) of vitamin C each day and compared their outcome with 1000 cancer patients given conventional therapy. The survival rate was five times higher in those taking vitamin C. By 1978, while all of the 1000 ‘control patients’ had died, 13 of the vitamin C patients were still alive, with 12 apparently free from cancer.
The overwhelming evidence is that a high intake of Vitamin C correlates with a low risk for cancer. In 1991, Dr. Gladys Block, formerly with the National Cancer Institute, published a review of Vitamin C research which concluded that there was very strong evidence of a protective effect of Vitamin C for non-hormone cancers. Of the 46 such studies in which a dietary Vitamin C index was calculated, 33 found statistically significant protection. After completing a further review in 1991, Dr. Block published a review later that year of studies linking Vitamin C with cancer prevention.
