Microwaves have shorter wavelengths but more frequency and energy than radio waves.

Microwaves can travel long distances.
Microwaves are used for cooking are transmitted using a magnetron inside the microwave appliance.
Microwaves in cell phones are transmitted using a transmitter chip and antenna.

Cell phone frequencies are also microwaves.
The health risks associated with cell phone use is not a myth.
The same microwaves which cook food and transmit cell phone communication can also penetrate the skull.
