Can B12 cure cancer?

Cancer - the dreaded C word! And the question whether Vitamin B12 has anything to do with it? Let's look at what we know:

Vitamin B12 is needed by cell DNA to switch off genes that aren't needed right now
most cells only need 1 or 2 genes switched on to perform their function. eg thyroid cells need the gene to produce thyroxin switched on, and nothing else. so they need lots of B12 to keep everything else switched off.
poisons like cigarette smoke and alcohol take B12 out of the body, leaving a whole lot of symptoms which are the same as B12 deficiency, because the B12 has left the body and the person actually does have B12 deficiency (obvious when you think about it)
lack of B12 means that genes can't be switched off. Genes left switched on could cause cancer (because most genes just manufacture more cells, ie tumours). So it's Vitamin B12 deficiency that causes cancer and B12 may cure it.

So where did the rumour come about?

researchers noticed that B12 all went to the cancer site and collected in the tumour. Most researchers immediately stopped the B12 supplements because they wondered if the B12 made the cells stronger. One team went on adding B12 and noticed that the tumours disappeared - they didn't get killed the way most cancer "cures" work, they went back to normal function and also went back to normal size.

Kind of better?

Frankie tells of how she suffered, the tests she had to endure until doctors worked out what was wrong, and what a difference it has made.

Donna, like so many women, wants to live a normal life. Vitamin B12 could give her that chance.

Susan gets very tired, which isn't much fun especially as she has so much to do. Here she tells her story.

Janette first appeared in the BBC InsideOut documentary in October 2006. Since then the NHS has forced her doctor to withdraw B12 replacement therapy on a number of occasions, and she tells of her struggles with having B12 and then having it taken away.
She has bravely agreed to be filmed without her usual wig, but her memory is playing up because it is so long since her last injection.

June describes her suffering when doctors didn't follow the standard protocol after any stomach or intestinal operation - to offer B12 replacement therapy

The local MP (Grahame Morris MP for Easington - who was a BMS (BioMedical Scientist) in the labs at Sunderland Royal Infirmary) interviews people with B12 deficiency to hear their story (August 27 2010). Here Jane describes the symptoms, and how she can't wait for her next B12 injection (in fact, she knows that she needs injections every 2 weeks because she's keeping a diary of the symptoms). We're restricted how often the GP can give injections, which is why we want to raise awareness.

Just the way it works for humans, oral B12 can make a world of a difference for your pet. My old cat Smudge chases the young cat again, climbs ladders (and climbs down herself), and is generally as fit as she was many years ago.

Julia found her eyesight going as her eyes refused to focus on the same things as each other. She's been for all sorts of tests and treatment, but now that she's on B12 replacement therapy she's starting to see an improvement.

New documentary out from Elissa Leonard in North America, featuring Sally Pacholok and many other internationally renowned experts.

The definitive and original guide to B12 deficiency, Dr Chandy interviewed by Chris Jackson of UK BBC Inside Out Team broadcast 31 Oct 2008.
