- (Reuters) -- Vitamin C can impede the growth of some
types of tumors although not in the way some scientists had suspected,
researchers reported on Monday.
- The new research, published in the journal Cancer Cell,
supported the general notion that vitamin C and other so-called antioxidants
can slow tumor growth, but pointed to a mechanism different from the one
many experts had suspected.
- The researchers generated encouraging results when giving
vitamin C to mice that had been implanted with human cancer cells -- either
the blood cancer lymphoma or prostate cancer. Another antioxidant, N-acetylcysteine,
also limited tumor growth in the mice, the researchers said.
- Antioxidants are nutrients that prevent some of the damage
from unstable molecules known as free radicals, created when the body turns
food into energy. Vitamin C, vitamin E and beta-carotene are among well-known
- Previous research had suggested that vitamin C may stifle
tumor growth by preventing DNA damage from free radicals.
- But researchers led by Dr. Chi Dang, a professor of medicine
and oncology at Johns Hopkins University in Baltimore, found that antioxidants
appear to be working in a different way -- undermining a tumor's ability
to grow under certain conditions.
- Figuring out how antioxidants impede tumors should help
scientists figure out how they might be harnessed to fight cancer, Dang
said. In addition to the cancer types involved in this study, others that
might be vulnerable to vitamin C include colon cancer and cervical cancer,
- Dang said more research is needed and cautioned against
taking high doses of vitamin C based on these findings.
- "Certainly we would very much discourage people
with untreated cancer to go out and take buckets full of vitamin C,"
Dang said in a telephone interview.
- Linus Pauling argued in the 1970s that vitamin C, also
called ascorbic acid, could ward off cancer, but the notion has proved
- Pauling, who won the Nobel Prize in chemistry as well
as the Nobel Peace Prize, died in 1994.
- "Pauling actually had some good evidence that under
certain situations vitamin C can prevent tumor formation. It's just the
mechanism was really not that clear then," Dang said.
- "Now that, I think, we provide relatively compelling
evidence of how this works, maybe Pauling is partly right. We shouldn't
dismiss him so quickly." Dang added.

- Critical Response To Vitamin C's Cancer-Fighting
- By Ken Adachi
- Dear Jeff,
- Re: http://www.rense.com/general78/csprop.htm
- How utterly vexing and annoying it was to read the salubrious,
yet untrue assertions made by oncologist and John Hopkins professor Dr.
Chi Dang concerning the role that Dr Linus Pauling played in the 1970s
in regard to heralding the importance of Vitamin C as a CRITICAL ingredient
in immune system modulation (enhancement) to not only PREVENT the formation
of cancerous tumors, but to ALSO mitigate and reduce the advancement of
cancer growth, once it had reached the full blown metastasis stage.
- Dr Dang, an obvious servant of the chemical cancer industry,
reduces the Herculean contributions in vitamin C knowledge provided by
Nobel laureate Dr. Linus Pauling down to that of a minor, peon researcher
whose discoveries merit no more mention than that of a footnote.
- I'd like to punch that guy square in the nose for uttering
such vapid stupidities!
- Long before this man showed up in a national press release,
Linus Pauling had ALREADY PROVEN and DEMONSTRATED THE many pathways by
which Vitamin C enhances immunity, and not only for cancer, but for ANY
- Pauling went FAR BEYOND tests with mice. He had already
graduated though ALL the ranks of animal research and was long ago engaged
in LONG TERM human studies (with Dr Cameron of Canada) in the EARLY 1970S!
He had published all of his research findings in numerous peer reviewed
journals and published no less than SEVEN Books documenting his findings!
- This is NOT the first time that I have encountered institutional
hacks from big name "medical research" universities or institutions
that have attempted to lay claim to discoveries that had ALREADY been documented
and published by earlier pioneers. About 6 years ago, I caught a brief
news item under new science discoveries in which a claim was made by a
female university "team leader" from a Big Deal university in
San Diego where she said that SHE had discovered some NEW and remarkable
attributes of Flax seed oil to stem cancer proliferation. I wrote her and
her adoring university promoters, that she hadn't discovered ANYTHING;
that her "work" was a virtual carbon copy of Dr Johanna Budwig's
research about flax seed oil made in the 1950s in Germany for which she
had to endure endless assaults and debunking travails from the entrenched
food oil industry in Germany.
- If you want to find out what Vitamin C can do to improve
health and immunity, then obtain the books of Dr Linus Pauling, published
in the 1970's and 1980s, and you will find out what this man will undoubtedly
lay claim to as "discovering" in the coming months and years.
- Long live the Corporate Foundation Research Grant and
the hacks who covet them, for they make life worth living for no
other reason than to rebuke their calumny and pretense to fame!
