In Dr Cui's lecture, he mentions the work of Dr Chester Southam at the Sloan Kettering Cancer Institute who injected cancer cells into willing volunteers in 1957, and only a couple of them actually died from this injection.

HOW RUDE! I guess they did not trust lab rats.

But it does attest to how strong the immune system really is.

I'm not convinced by Dr Cui's cancer world map shows that its vitamin D alone that is responsible for lower cancer rates.

Russia for instance has an average lower age of death than most countries which means a lot of cancers formed in the 70/80 year olds will not be formed in Russia's population.

The other Elephant in the room is why Mexico adjacent to the US, has only 1/3rd the rate of cancer of the US, especially when their average vitamin D levels are
low(under 75 nmol/l), not much different than US.

A similar reason could be put forward for the lower rates in lots of Middle East and African countries, who despite having plenty of sunshine still have low vitamin D levels and lower cancer rates.

The real question that should be asked is why the 3 major areas with Western diets, US, Western Europe and Australia & New Zealand appear to have the highest cancer rates irrespective of the amount of sunshine.

I don't think anything can stand alone for lower cancer rates. If anything, USA municipal water supply may have chemicals that affect our assimilation of vitD or other essentials. This may not be true of other countries, especially poorer countries.
