My Malignant Melanoma

There's been some posting recently on Cancerbacup's message boards about Vitamin D and cancer prevention.

Whilst this is not as ridiculous as all other claims for megavitamin therapy, the evidence is presently inconclusive as far as Cancer Research UK and the NHS are concerned:

CRUK
NHS

The poster on the subject also failed to understand that the study showing poor prognosis associated with low vitamin D levels did not prove that low vitamin D was responsible for poor prognosis. It showed that one followed the other, but day does not cause night. It is false reasoning to say that if something follows something else, the first necessarily caused the second.

In any case, as ever, prevention is not cure. Even if a higher RDA for vitamin D did have beneficial effects on the incidence of some cancers, that's a bit late for those of us already diagnosed, and recommending sunbathing to melanoma patients would be highly contentious.
