Interesting article - but I'm left to wonder how it applies to where I live - we have a two month polar day in summer - but AFAIK no increased incidence of cancer.

There's a lot of research going on effects in humans - but admittedly I'm not really up to date.
I do recall this one that's tangentially releated:
