Vitamin C injections 'stop spread of cancer' in
rodents

By Steve Connor, Science Editor

Injections of vitamin C can stop the spread of
cancer and slow the growth of tumours by 50 per
cent in tests on laboratory mice, scientists said
yesterday.

The effect was seen on a variety of cancers, such
as those of the brain, ovary and pancreas,
although the researchers emphasised that further
research was necessary before it can be tested on
humans.

The idea that vitamin C, which is found in fruit
and vegetables, could help to fight cancer goes
back more than 30 years, but it fell out of favour
when studies where the vitamin was given orally
failed to live up to expectations.

But a US government-funded study, published in the
journal Proceedings of the National Academy of
Sciences, found that directly injecting high doses
of vitamin C, or ascorbate, into the body can
produce significant improvements in the health of
mice with cancerous tumours.

Mark Levine of the US National Institute of
Diabetes and Digestive and Kidney Diseases in
Bethesda, Maryland, said that it was possible to
raise ascorbate levels in the body to a point
where they became pharmacologically active, which
does not occur when the vitamin is taken orally.

But Dr Alison Ross of the charity Cancer Research
UK said: "There is no evidence from clinical
trials in humans that injecting or consuming
vitamin C is an effective way to treat cancer.
Some research even suggests that high doses of
antioxidants can make cancer treatment less
effective, reducing the benefits of radiotherapy
and chemotherapy."
