"Microwave" is an arbitrary term, signifying radio frequencies above 1
GHz.  This spectrum includes the "PCS" cell phone band, WiFi, many
cordless phones etc.  Microwaves have not been demonstrated to cause
cancer, as they are not ionizing radiation.  Ionizing radiation, such as
the upper ultraviolet frequencies, X-rays etc., does cause cancer.
However, excessive levels of microwave energy can cause other problems,
due to heating effects.
