Is microwaving food unhealthy? Does it change the food in anyway?

My roommate is on an antimicrowave kick, spouting off claims that microwaves cause cancer, etc. Can you shed some light on this subject for me?

Highly unlikely. Microwaves can only generate increases in rotational modes, which relax by giving off heat. You have to get up into the UV before the photons have enough energy to generate electronic transitions that can lead to molecular rearrangements, which is what could potentially cause cancer. Microwaves can't do anything but generate heat.
