The microwave oven uses very similar radio frequencies to a cellphone.
However, the way that a microwave oven causes damage to animal flesh is
by heating it via excitation of the water molecules in it. The power
output of a cellphone is three orders of magnitude below a typical
microwave oven, in addition to which the microwave emitters are
designed to concentrate their power rather than radiating it uniformly.

A cellphone emits far too little power to cause any damage by heating,
and no other mechanism has been posited for it to harm people.

The bottom line: the science is in, and there is abundant reason to
believe that cellphones do not directly cause harm of any kind. If you
rear-end a cement truck on the freeway because you were yakking on your
cell, that's not the phone's fault.

Anything else is just crying wolf.
