What the hell's going on in Australia? I was thinking food supply and all the radio/cell/electricity waves in the air might contribute to the US, but I can't see how that would apply the same in Australia....?

I was going to ask the same thing. Here in the U.S. I think it comes down to diet more than anything. I don't have any insight into Australian dietary habits though.

Also, it's hard to tell, but it looks like a a few European countries are as bad as the U.S. France, Portugal and maybe a couple of others.

Junk food and processed food primary reasons.

Oh wow we have a lot in Australia. Although skin cancer is bad here I think it is due to the ozone layer.
