Can RF radiation cause cancer?

This silly question just refuses to go away.
Finally after 11 years NTP released a report. And, waaah, they found something.

Really? What about scaling to humans, publication bias, statistical significance,  realism, ...

And also - of course it is cancerogenus. Seriously, I am sure it is. But what is not? If we would apply the same care with tobacco,  alcohol,  sugar,  fat, chemicals, fossil fuel residues, well, most things that are nice. Not much would be left. Isn't there better ways to spend $25M?
