Current scientific evidence suggests that microwave ovens do not cause cancer. The World Health Organization (WHO) and the American Cancer Society both state that the levels of non-ionizing radiation emitted by microwave ovens are not strong enough to cause cancer. The microwaves are contained within the oven and are only present when the device is operating. Additionally, microwave ovens are designed with safety features such as metal screens and door interlocks that prevent radiation from escaping.
