that is very interesting -- it is kind of scary to think that a recommendation of a vitamin or medicine which could contain antioxidants could cause more harm than good to a patient fighting cancer -- g.ps may not be aware of this - as they are not specialied in a particular field - and only have general knowledge of alot of the treatments out there to fight cancer.

This news makes me feel like I'm putting nails in the coffin. I'm exhausted from searching and looking for information about cancer cures.

I, too, find these early results daunting. How to know when we are helping or hurting our odds?

I take prescribed supplements some of which are antioxidants. Even thought this research adds complexity to my next steps, I do value you sharing it.

In a paper that he published at this time last year, Dr. James Watson (co-discoverer of the DNA double-helix configuration) alluded to this exact same thing - more specifically with the resistance to ROS in late-stage cancers. I was intrigued by this brilliant minds take on the dismal failure of the War on Cancer started back in the 70's by President Nixon. It's a great paper to read and not too technical. although it had taken me some time absorb.

Well, that's just great!  I have just been diagnosed with the beginnings of macular degeneration, and my opthomologist prescribed special vitamins for that ailment, which have very high doses of vitamins A,C, and E.  What am I supposed to do now?

I learned a long time ago that Vitiamine E caused rapid cell growth. So this is not surprising

Natural Vitamin E Prevents, Reverses Lung Cancer
Your "Pharmaphilic" Media Botches Another Story

by Andrew W. Saul, Editor

(OMNS Jan 31, 2014) Yet another media hatchet job on vitamin E is, predictably, getting lots of attention. This particular attack is just one more in an embarrassingly long series. It is based on a recent study proclaiming that vitamin E promotes cancer. (Sayin et al. Antioxidants accelerate lung cancer progression in mice. Sci Transl Med 29 January 2014: 6: 221 http://stm.sciencemag.org/content/6/221/221ra15 )

Well, with a highfalutin' study like that, they might at least have used real vitamin E.

They didn't.

I have searched the original paper. They mention "vitamin E" over and over and over again. However, the words "d-alpha tocopherol," or "mixed natural tocopherols," do not appear in the paper, at all, except in one reference citation. Why? Because that is what natural vitamin E is called. If the researchers had taken the trouble to use natural vitamin E, it would likely have reduced cancer. For example:

Taking 300 IU of natural vitamin E per day reduces lung cancer by 61%. (Mahabir S, Schendel K, Dong YQ et al. Dietary alpha-, beta-, gamma- and delta-tocopherols in lung cancer risk. Int J Cancer. 2008 Sep 1;123(5):1173-80.) http://www.ncbi.nlm.nih.gov/pubmed/18546288
Of Course Synthetic Vitamin E is Less Effective

With a careful search through a lot of jargon, you will discover that the negative study used DL-a-tocopheryl acetate, a synthetic pseudo-vitamin E. However, real "vitamin E" is actually eight different biochemical forms, alpha-, beta-, delta- and gamma tocopherols, and alpha-, beta-, delta-, and gamma-tocotrienols. The much-touted "vitamin-E-causes-lung-cancer" study ignores this. I believe that the authors were so embarrassed that they selected synthetic vitamin E, which almost anyone knows to be inferior, that they quietly stated only once, in their entire paper, what kind of "E" they used. If I am wrong, let them prove otherwise. OMNS invites and will publish their rebuttal to this editorial.

And, the authors utterly ignored tocotrienols. Look for that word in their study condemning vitamin E. Look really hard. It is not there. The word tocotrienol does not appear in the paper. Not once.

Why? Because gamma tocotrienol is known to destroy cancer stem cells.

Research published in the International Journal of Cancer has shown that gamma-tocotrienol, a cofactor found in natural vitamin E preparations, actually kills prostate cancer stem cells. These are the very cells from which prostate cancer develops. They are or quickly become chemotherapy-resistant. And yet natural vitamin E complex contains the very thing to kill them. Mice given gamma-tocotrienol orally had an astonishing 75% decrease in tumor formation. (Sze Ue Luk1, Wei Ney Yap, Yung-Tuen Chiu et al. Gamma-tocotrienol as an effective agent in targeting prostate cancer stem cell-like population. International Journal of Cancer, 2011. Vol 128, No 9, p 2182-2191. http://onlinelibrary.wiley.com/doi/1...25546/abstract )
Gamma-tocotrienol also is effective against existing prostate tumors. (Nesaretnam K, Teoh HK, Selvaduray KR, Bruno RS, Ho E. Modulation of cell growth and apoptosis response in human prostate cancer cells supplemented with tocotrienols. Eur. J. Lipid Sci. Technol. 2008, 110, 23-31. http://onlinelibrary.wiley.com/doi/1...00068/abstract. And: Conte C, Floridi A, Aisa C et al. Gamma-tocotrienol metabolism and antiproliferative effect in prostate cancer cells. Annals of the New York Academy of Sciences, 2004. 1031: 391-4. http://www.ncbi.nlm.nih.gov/pubmed/1...t=AbstractPlus
Set Up to Fail

Synthetic vitamin E was selected. It did not work. Natural vitamin E was not used. Tocotrienols were not used. I challenge any scientist or journalist to try to explain these omissions away.

Based on USDA data ( http://lpi.oregonstate.edu/infocente...mins/vitaminE/ ; scroll down to "Deficiency"), an astonishing 90% of Americans do not get the RDA of vitamin E.

Tell people not to take vitamin E, and they will be dropping like flies. The medical media should be ashamed of themselves.

Vitamin E Prevents Lung Cancer
News Media Virtually Silent on Positive Vitamin Research

(OMNS, October 29, 2008) Researchers at the University of Texas Anderson Cancer Center have found that taking more vitamin E substantially reduces lung cancer. Their new study shows that people consuming the highest amounts of vitamin E had the greatest benefit. When they compared persons taking the most vitamin E with those taking the least, there was a 61% reduction in lung cancer risk. (1)

Lung cancer is the most prevalent form of cancer on earth; over 1.3 million people are diagnosed with it each year. With medical treatment, survival rates are "consistently poor," says Cancer Research UK. Lung cancer kills nearly 1.2 million per year. It accounts for 12% of all cancers, but results in 18% of all cancer deaths. (2) Anything that can reduce these dismal facts is important news . . .very important. Yet the mainstream media have virtually ignored vitamin E's important role as a cancer fighter.

A sixty-one percent reduction in lung cancer with vitamin E? How could the news media have missed this one?

The news media probably did not miss it: they simply did not report it. They are biased. You can see for yourself what bias there is. Try a "Google" search for any of the major newspapers or broadcast media, using the name of the news organization along with the phrase "vitamin E lung cancer." When you do, you will find that it will quickly bring up previous items alleging that vitamin E might (somehow) increase cancer risk. You will find little or nothing at all on how vitamin E prevents cancer. Indeed, the bias is so strong that even a qualified search for "increased vitamin E reduces lung cancer" will still, and preferentially, bring up media coverage alleging that vitamin E is harmful. Negative reporting sells newspapers and pulls in viewing audiences. The old editors' adage must still be true: "If it bleeds, it leads."

Here's more positive vitamin E cancer research that the media "missed." A study in 2002 looked at patients with colon cancer "who received a daily dose of 750 mg of vitamin E during a period of 2 weeks. Short-term supplementation with high doses of dietary vitamin E leads to increased CD4:CD8 ratios and to enhanced capacity by their T cells to produce the T helper 1 cytokines interleukin 2 and IFN-gamma. In 10 of 12 patients, an increase of 10% or more (average, 22%) in the number of T cells producing interleukin 2 was seen after 2 weeks of vitamin E supplementation." The authors concluded that "dietary vitamin E may be used to improve the immune functions in patients with advanced cancer." That improvement was achieved in a mere two weeks merits special attention. (3)

Was it on the news? Did you hear about how high doses of vitamin E help cancer patients' immune systems in only two weeks? Why not? Might the answer possibly have anything to do with money? One cannot watch television or read a magazine or newspaper without it being obvious that drug company cash is one of the media's very largest sources of revenue. Given where their advertising income comes from, it is hardly a big surprise that media reporting on vitamins is biased. Well-publicized vitamin scares feed the pharmaceutical industry. Successful reports of safe, inexpensive vitamin therapy do not.

One commentator has observed that pharmaceutical and other "corporations marshal huge public relations efforts on behalf of their agendas. In the United States the 170,000 public relations employees whose job it is to manipulate news, public opinion and public policy in the interests of their clients outnumber news reporters by 40,000." (4) Another commentator wrote that "Janine Jackson of Fairness and Accuracy in Reporting (FAIR), a news media watchdog group, told the American Free Press that 60 percent of journalists surveyed by FAIR admitted that advertisers 'try to change stories (and) there is an overwhelming influence of corporations and advertisers' on broadcast and print news reporting." (5)

Drug companies don't have any drug that can reduce lung cancer risk by 61%. If they did, you would have heard all about it in their advertisements. And it would be all over the news. Positive drug studies get the headlines. Positive vitamin studies rarely do. This is an enormous public health problem with enormous consequences. A cynic might say that press and television coverage of a vitamin study tends to be inversely proportionate to the study's clinical usefulness. Truly valuable research does not scare people; it helps people get well. It would be difficult to identify anything more helpful than actively reporting the story when a vitamin is shown to reduce lung cancer by 61%.

The good news about how important high quantities of vitamin E are in combating cancer is not arising out of nowhere. A US National Library of Medicine MEDLINE search will bring up over 3,000 studies on the subject, some dating back to 1946. By the early 1950s, research clearly supported the use of vitamin E against cancer. (6) Before 1960, vitamin E was shown to reduce the side effects of radiation cancer treatment. (7) In reviewing vitamin E research, one notes that the high-dose studies got the best results.

Vitamin E is not the sure cure for cancer. It is not certain prevention, either. Stopping cigarette smoking is essential. But vitamin E is part of the solution, and we need more of it. An independent panel of physicians and researchers (8) has recently called for increasing the daily recommended intake for vitamin E to 200 IU. The present US RDA/DRI is a mere 15-20 IU/day.

It is time to raise it. A lot.
