We know that when light of certain frequencies is shine on any organic system, it reacts coherently, like it inhaled the light, then exhaled it. This is a principle piece of evidence for the biophoton theory, as dead systems do not react this way. They react just like the unintelligent mattet that ignorant claim we are made of.
Here is my idea: wherever the tumor is, find the frequency at which the healthy tissue responds, and take turns irradiating it, then letting it shine back out, in an analogy to breathing. Over some period of time it should reactivate the light sensors, and bring the diseased tissues back into the system.
Actually, I may have said this exact idea already. My brain gets full sometimes and purges files.
What seems CERTAIN is that no cancer cure thst is more intelligent than a club and a knife will be forthcoming until scientists are willing to get beyond their dogmstic ignorance.
