Microwaves can cook you, yes. At high power. Defeating the interlock and sticking your head in would be a bad idea, but you are looking at 800 watts to 1.5 Kilowatts, and at a much higher frequency (2.4GHz). Frequency matters as well as power.
3 watts at 800Mhz isn't going to penetrate the skin, let alone the underlying muscle and bone, to affect your brain.
Edit: Here's how to tell it's NOT penetrating the skin. Your ear would get warm when you used your cell phone. Doesn't happen.
Microwaves cook because water absorbs the energy, because water resonates at the frequency of microwaves. All sorts of molecules in the body resonate at different frequencies. Just because the nerves in your ear don't register warmth doesn't mean that other molecules in your body aren't absorbing energy. The body has few sensory nerves below the skin anyway.
The amount of energy is much smaller, yes, but it is also quite concentrated. I'm not saying there is an effect, I just don't know, but it is possible and it is definitely worth studying.

Especially around lots of mitosis, I would imagine.
