Technology is taking the lead in our everyday living, as part of this microwave is an essential utility in a modern kitchen today.
I got stocked when a friend totally condemned the use of microwave stating the effects it has on consuming food warmed wit it..but I really find it difficult to adhere thinkin of the benefit and time saving it could be most times especially on cold/froze foods.
He said he got the info from the internet..since being told I decided to ask if its true that microwave as the effect of causing Cancer like he said..

Since microwaves are a form of energy, they can affect humans, just like the sun or other energy sources can. Our skin does not like to be bombarded with energy sources.

Make sure that the door seal is kept clean and not torn. Standing near one leaking microwaves is not beneficial, and we could get burnt. The skin will redden like sunburn or get a worse burn depending on our exposure.

He was talking about the effect on d food we eat..that eating microwaved food is not ideal, that I checked on the internet and got loads of disadvantages.

I think your friend is right, it can harm humans.

How?
