I have wondered if the cure to cancer might come not from chemicals or radiation, but from some sort of sound/vibratory therapy. My reasons for thinking this? Almost new-agey, in that “vibrations” constitute music and harmony (if done properly), and harmony implies order and healing. Blast away, I don’t care.
Blast away? Hardly. Your idea has been around for just about a hundred or so years, maybe longer. A sci-fi novel by Robert Heinlein, written in the early 1940's but not published until after the war, had as one of its 'predictive elements' a device that could cure practically any disease simply by 'tuning' it to the proper 'frequency' for that person and their disease.
There have been scams using the idea as well, getting desperate terminally ill people to pay for 'treatments' and 'therapies' that involve fancy words like "electro-magnetic resonances" and such, even to this day.
I have thought that there is a 'resonant frequency' for each cell type that only those cell types will respond to. We have all seen that if you hit the resonant frequency of a crystal wine glass with enough power, it will shatter. Also, we have seen the film of the 1940 original Tacoma Narrows Bridge collapse because of its resonance with the wind. I would think that the same thing would happen with a cancer cell.............. https://en.wikipedia.org/wiki/Tacoma_Narrows_Bridge_(1940) https://www.youtube.com/watch?v=dXL3GdZlw88
