Very interesting.
I have thought about it as well.
Like a crystal wine glass being shattered by a sound, a cancer cell must have a fundamental frequency that it is vulnerable to, that would leave healthy cells undisturbed.
Different cancers would, of course, require different frequencies, maybe even changing from person to person.
But i believe it is possible...................
Cool stuff, but equally scary. I imagine what would happen if humans cells were easily controlled by radio waves. Imagine what someone could do.
