The Real Story of Vitamin C and Cancer

By Steve Hickey PhD and Hilary Roberts PhD

In the last couple of days, vitamin C and cancer has be come a hot news topic. For people who have followed this matter, the media's sudden interest comes as some thing of a surprise: the evidence that vitamin C is a selective anticancer agent has been known for decades . This story is important , as it illustrates how the head - in - the - sand conventional view ( that nutritional supplements are useless ) can lead to restrictive legi slation, reduced health, and limit ed approaches to the treatment of disease.

The recent news story arose from a study by researchers at the US National Institutes of Health (NIH). 1 The NIH experiment showed that , when injected into mice, vitamin C could s low the growth of tumours. The NIH paper presents its findings as new , ignoring the long history of research into vitamin C and cancer. Far from being novel , many of the findings reported in this paper have been recognized for decades. What is strange, how ever, is that the media suddenly decided to report a story they had ignored for so long.

A history

One strand of this story begins with the work of an old friend , Dr Reg inald Holman . In 1957, Holman published a paper in Nature about how hydrogen peroxide ( the chemical Marilyn Monroe reportedly use d on her hair) destroyed or slowed the growth of tumours in mice . 2 Reg Holman met with some hostility from the medical profession, which slowed his research and clinical work over the following half century. Neve rtheless , scientists have known that hydrogen peroxide kills cancer cells for over fifty years

In 1969, when man first walked on the moon, researchers found that vitamin C would selectively kill cancer cells without harming normal cells. 3 That finding me ant that vitamin C was like an antibiotic for cancer: potentially a near perfect anticancer drug. Before 1970, it was known that vitamin C was an example of a new class of anti cancer substances. However, the medical research establishment largely ignored t hese scientific results

In the 1970s , some members of the public and pioneering doctors experimented with high doses of vitamin C to treat cancer. By 1976, double Nobel Prize winner Linus Pauling and Scottish surgeon Ewan Cameron reported clinical trial s , showing an unparalleled increase in survival times in terminal cancer patients treated with vitamin C. 4 However, by this time Pauling was considered a quack , having claimed that vitamin C could prevent or cure the common cold , so these apparently amazin g findings made little impact .

Cameron and Pauling published a second report in 197 8 . 5 The Mayo Clinic responded with a study that suggested vitamin C had no effect , which the medical profession readily accepted, perhaps because it confirmed existing pre judices . However , despite the Mayo Clinic study being " considered definitive " , 1 it was highly criticised from the start . In particular, it used relatively low oral doses for short periods , rather than the lifet ime combination of high oral and intravenous (IV) doses in the Pauling and Cameron study. The Mayo Clinic refused to provide Pauling with their data so he could check it. When we emailed the Mayo Clinic with a similar request, we received no reply

If Cam eron and Pauling 's work , back in the 1970s , had been just a single study, it would have been interesting and suggestive. Such a large increase in survival time demands a proper scientific follow - up and, indeed, other studies soon backed up the findings. Ja panese researchers found similar survival times, 6 apparently confirm ing Pauling's early results. Subsequently, Dr Abram Hoffer , working in Canada , provided more evidence that vitamin C could enable cancer patients to live much longer. W e have analysed thes e results and found them to be statistically valid . They are not explicable by placebo effect or by a simple biased selection of long - lived patients. Moreover, over the last three decades , a large number of clinical and anecdotal patient reports support th e claims

A long time before the NIH's mouse experiment, Pauling also studied the effects of vitamin C on cancer in mice. He worked with Dr Art Robinson but, unfortunately, the two researchers fell out over the ir interpretations of the results. Robinson l eft the Linus Pauling Institute (which he had helped establish ) and completed the experiment alone. It was eventually published in 1994. 7 The results were outstanding : mice with cancer that were given high dose vitamin C in the diet , or fed a diet of raw v egetables , lived up to 20 times longer than controls . Translate d into human terms , this might mean that a person with one year to live might get an extra 20. Importantly, Robinson and Pauling had been inspired to do this experiment by claims from cancer su fferers in the popular literature .

Doctors Hugh Riordan, Ron Hunninghake , Jim Jackson , Jorge Miranda - Massari, Michael Gonzalez and others in the Brightspot Center f or t he Improvement o f Human Functioning , did the core research on vitamin C and cancer. The y repeated and extended the early work, which had showed vitamin C would selectively kill cancer cells. They have years of experience of treating cancer patients with high dose vitamin C. Their work is consistent with results from independent researcher s a nd doctors worldwide. 8

The authors of this article recently reviewed the literature on vitamin C and cancer, in our book "Cancer: Nutrition and Survival". 8 We found solid evidence that vitamin C , in high enoug h doses , act s a s a selective anticancer drug. Furthermore, an understanding of its action provides insight into the cancer development process . O xidants , such as hydrogen peroxide , are able to make cells grow and divide erroneously . So, a s the cells divide , they form a population of varying cells that compete with each other for survival. It was immediately clear that oxidation could explain how cancer starts; following which Darwin's theory of evolution takes over. G iven enough time , cells divide and the " fittest" are selected. I n this context , the fittest to survive are those cells that grow rapidly to form an invasive cancer. Cancer is not a mysterious disease but is a result of straightforward biological processes .

This microevolutionary model for cance r makes highly specific predictions. One is that h igh dose vitamin C should prevent cancer and even higher doses should kill cancer cells . The model also predicts that t here could be thousands of selective anticancer drugs . Animals , and especially plants , will contain these substances , because they evolved in the presence of cancer and had to develop ways to control it . If such predictions are correct, we should find a multitude of safe anticancer agents in food. C heck ing against medical databases, we immed iately found numerous examples, such as c urcumin from turmeric, alpha - lipoic acid, and vitamin D3 . Everywhere we looked, we found su bstance s with the predicted properties . Unfortunately, many are the very supplements the Alliance for Natural Health (ANH) i s trying to protect from being banned!

T o conclude our history, t he NIH paper was essentially a repeat of previous animal experiments . Despite this, the NIH authors appear not to have referenced many of the scientists who did the original work on vitamin C and hydrogen peroxide in cancer . Instead, they present their work as stand ing alone , in an informational vacuum: with the exception of the Cameron and Pauling clinical trial, the original scientists' work is not mentioned in the NIH text. Wrongly, a read er might gain the impression that the NIH's work was fundamentally original , rather than repeating the work of others. This might mislead the media into ascribing credit for the work on vitamin C and cancer to the NIH , which would be unfair to the real pio neers of this subject.

Comments from Dr. Levy

Drs. Hickey and Roberts have written a revealing report on the abilities of vitamin C to effectively treat cancer. In so doing, they also reveal many of the most common criticisms that are leveled against any therapy that threatens the status quo or any other mainstream therapy. In the case of vitamin C research, in general, the patterns that continue to emerge to this day include:

  • The ignoring of an incredibly huge body of peer-reviewed literature reported in a wide variety of journals, including the "traditionally reputable" ones
  • Academically dishonest or shamefully ignorant "modern-day" researchers trying to take credit for what has been already been well- established in the literature
  • The incessant conclusion that although the findings of any study might be good or even impressive, "more research and study" needs to be done with a virtually non-toxic nutrient like vitamin C, made even more ridiculous by the rapidly embraced utilization of countless, highly toxic prescription medicines
  • The regular conclusion in many different studies that vitamin C is not effective, at any dose, for a given condition when extraordinarily tiny doses of it have been studied
  • The making of egregiously unfounded comments either against the use of vitamin C or in support of a competing treatment modality, continuing to try to drain the collective energies of honest scientists who feel compelled to go to great lengths to explain why such comments are outrageous

I would like to add one further comment about this report. Drs. Hickey and Roberts discuss what they would do should either of them develop cancer. Their approach is very sound, but it needs to be added that a total dental revision should always be part of any clinical approach to treating cancer, mainstream or otherwise. Vitamin C is important in treating cancer primarily because the prooxidative, electron-depleting, effects of an undiagnosed toxicity or source of toxicity in the body have not been addressed, and the collective body store of antioxidants is always substantially depleted. Root canal treated teeth and periodontal disease continuously release toxins of an extraordinary potency. Ultimately the presence of these conditions, by virtue of their relentless ability to deplete vitamin C and other antioxidant stores, is the single primary reason for the both the development of a very large number of cancers as well as their often inadequate response to whatever therapy is utilized.
