Radiotherapy has been used to treat cancer.
Can the resonances by coordinated electromagnetic waves (and/or other forms of waves), of various frequencies, amplitudes and pulse rates, directed from various directions, be used to destroy harmful viruses, bacteria or cancer cells in a human body, without damaging the other parts of the human body?
(* NOTE * This question was posted here in Physics Stack Exchange too, but is possibly going to be closed in that forum as some claimed it is not so much about Physics.)
