Susan!!!
RFA (Radio Frequency Ablation) or cryotherapy on wikipedia says they use it actually for heart treatments.
The cyberknife actually uses radiation (X-rays to be exact, non?) notfrequencies, so I assume you're talking about RFA.
That's why I got this threaded blog, because this stuff is so complicated, and it takes time to research and who better to do that and share than my, the Victim??
