Question 998

Is it true that microwaves cause cancer?
I think that it's very unlikely that microwaves cause cancer. Microwaves are not ionizing radiation—they don't directly damage chemical bonds. Instead, they heat materials, particularly those containing water. As a result, they may cause damage to proteins in the same way that cooking damages proteins (and hardens egg protein, for example). But while such protein damage can easily cause cell death, I wouldn't expect it to cause the genetic damage associated with cancer.
