Do Microwave Ovens Cause Cancer?
People are generally skeptical about microwave ovens. However, microwaves operate using Radiofrequency (RF) on the electromagnetic spectrum. The RF waves from microwaves are more concentrated than everyday radiation but even so it is safely contained within the microwave unit. Microwaves do not use x-rays or gamma rays which are on the higher end of the radiation spectrum. There is no evidence that when used correctly microwaves pose health risk.
However, it is better not to press your face against the window of the microwave and keep at least one - foot distance from the oven.
