Can microwave ovens cause cancer?
Microwaves lack the ability to change cell structure, and despite concerns there is no proof that exposure to them can cause cancer
While they may be exceptionally convenient, microwave ovens aren’t without their share of controversy. There have been concerns that using one can strip your food of its nutritional content and even cause cancer. But is any of this true?
A microwave oven is powered by a magnetron, an electronic tube that emits microwaves (low-frequency electromagnetic energy). Microwaves are non-ionising (meaning they are not powerful enough to knock electrons out of atoms and thereby alter the DNA of cells; see ‘Types of radiation’, above). Once emitted, these are reflected in all directions by the metal inner walls and absorbed by the food, thus heating it up.
The World Health Organization (WHO) website states that ‘current evidence’ does not confirm the existence of any health consequences from exposure to low level electromagnetic fields.’
