That's one study in what? A million of them?

Let's not forget ourselves. Radiation isn't some freaky thing. It's a well understood physical phenomenon. It's not rocket science. It's an electromagnetic field propagating through space. We happen to have two good sensors that measure it in some ranges.

When radiation hits any matter, it does one thing and one thing only, it transmits energy. When an atom is struck by energy, it's electrons get excited and move from their rest positions. When the radiation goes away, they go back to their rightful places, and release heat.

Now the energy needed to move an electron 'up a layer' is quantified (get it? this is partially where Quantum Mechanics comes from) meaning if you keep giving it the same amount of energy, it will just keep the same, higher state. You need to send it more energy to bring it to a higher state. When radiation with enough energy hits an atom, one of the electrons will actually bounce off. AND BOOM we get an ion.

Now radio frequencies will always radiate the same energy, since they have the same frequency. I'm not going to prove it here, but they're proportionally related. The higher the frequency, the higher the energy. So there's no way a radio frequency actually emits enough energy to ionize an atom. That's why we call that radiation 'non-ionizing'.

Radiation derived cancer, as far as we know, happens when atoms from your body become ions. Your body is not quite ready for that, and it will mostly just kill off that cell. However, some DNA damage might simply ruin it the wrong way, and make that cell never die, and constantly reproduce. That's cancer.

Now, unless new medical discoveries prove that heat causes cancer, which would be quite a bit more troubling than 'phones cause cancer'. there's no way radio frequencies are causing cancer.

It's like saying cold water is drying people. It's just not something water does. The only thing radiation does is heat you up. Nothing more, and nothing else. Trying to convince people of understood phenomenons properties with small statistic based studies isn't gonna work that well.
