Vitamin C slows down cancer

Vitamin C Slows Cancer Down
And, Doctors Say, Can Reverse It as Well

(OMNS, October 31, 2008) The BBC recently reported (1) that "Vitamin C 'slows cancer
growth.' An injection of a high dose of vitamin C may be able to hold back the
advance of cancers, US scientists claim. The vitamin may start a destructive chain
reaction within the cancer cell." The injection "halved the size" of tumors, and was
reported in the Proceedings of the National Academy of Sciences.

The study authors themselves said that daily, high-dose vitamin C treatment
"significantly decreased growth rates" of ovarian, pancreatic, and malignant brain
tumors in mice. Such high, cancer-stopping levels of vitamin C can be "readily
achieved in humans given ascorbate intravenously." (2)

"Readily achieved"? Then this is important, absolutely vital news for millions
fighting or fearing cancer.

So what do major cancer organizations have to say? Not much. That is disappointing,
but hardly surprising. Both the American Cancer Society and Cancer Research UK have
downplayed or flatly ignored decades of physician reports and controlled clinical
studies indicating that vitamin C stops cancer. What's worse, each of these
supposedly comprehensive cancer research and education organizations continues to
actively discourage people from using vitamin C against cancer.

Look for yourself and see. The American Cancer Society's vitamin C webpage (3)
specifically states: "Although high does of vitamin C have been suggested as a
cancer treatment, the available evidence from clinical trials has not shown any
benefit." And Cancer Research UK states that "There is currently no evidence from
clinical trials in humans that injecting or consuming vitamin C is an effective way
to treat cancer." (1)

"No benefit," they say. "No evidence," they say.

Both organizations are wrong. Neither statement is true.

In 2008, Korean doctors reported that intravenous vitamin C "plays a crucial role in
the suppression of proliferation of several types of cancer," notably melanoma. (4)

In 2006, Canadian doctors reported on the effectiveness of intravenous vitamin C in
treating cancer. (5)

In 2004, doctors in America and Puerto Rico published clinical cases of vitamin C
successes against cancer. (6)

In 1990, American doctors published their results successfully using vitamin C to
treat kidney cancer (7). In 1995 and 1996, other cancers. (8) Using 30,000 mg of
intravenous vitamin C twice per week, they found that "metastatic lesions in the
lung and liver of a man with a primary renal cell carcinoma disappeared in a matter
of weeks. . . We subsequently reported a case of resolution of bone metastases in a
patient with primary breast cancer [1A] using infusions of 100 grams, once or twice
per week." (9)

In 1982, Japanese doctors showed that vitamin C greatly prolonged the lives of
terminal cancer patients. (10)

And as early as 1976, over two decades ago, physicians in Scotland showed that
intravenous vitamin C improved quality and length of life in terminal cancer
patients. (11)

Why are ACS and Cancer Research UK oblivious to the weight of evidence? All these
previous clinical reports were published in peer-reviewed medical journals. One may
bear in mind that both ACS and Cancer UK made their restrictive statements August
2008. Yes, 2008. In spite of increasingly compelling evidence for 22 years, both the
American Cancer Society and Cancer Research UK are dragging their feet.
Foot-dragging costs lives. Hundreds of thousands of people have died from cancer
that could have been helped with ascorbate therapy. But for decades, their three
advocated cancer treatments have been "cut, zap, and drug": surgery, radiation and
chemotherapy. The use of high doses of vitamins has been thoroughly excluded.

Indeed, ACS still says: "If a supplement is taken, the best choice for most people
is a balanced multivitamin/mineral supplement that contains no more than 100% of the
'Daily Value' of most nutrients." (3) That is harmful advice. Many well designed
clinical studies show that large doses of vitamin C and other nutrients improve both
quality and length of life for cancer patients. The key is the use of sufficiently
high quantities, appropriately administered. More orange juice just won't do it.

Cancer Research UK even maintains (1) that vitamin C "can make cancer treatment less
effective, reducing the benefits of radiotherapy and chemotherapy." That statement
is untrue. (12,13) Oncologists routinely administer antioxidant drugs along with
chemotherapy with no diminution of effect. (14)

ACS and Cancer Research UK say that there is "no evidence from clinical trials" that
vitamin C is any good against cancer. They should start reading the medical
literature. They are way behind the times. And they are wrong. Dead wrong.
