Microwaving water

Asked January 11, 2018, 11:03 AM EST

I recently was told that microwaving water, rather than heating on a stove, is dangerous and has cancer causing properties. Is this true? Janet

Hi Janet,
It is possible (but not very likely) that microwaving water can cause burns due to "super-heating." You can reduce the risk by using the least amount of time needed to boil the water. See more from the FDA here: https://www.fda.gov/Radiation-EmittingProducts/RadiationEmittingProductsandProcedures/HomeBusinessan...

As for cancer-causing properties, the American Cancer Society states that there is no risk because the waves are contained within the microwave oven (as long as your microwave isn't damanged). See more here: https://www.cancer.org/cancer/cancer-causes/radiation-exposure/radiofrequency-radiation.html
