Yes, the world of "Cancer" is horrifying.
I used to work in the "Cancer" industry; never have i seen a more retched hive of scum and villainy.

I like the paths you have gone down in searching out solutions for what is cancer, and what to do about it.

What is cancer?

Cancer is an emotional dis-ease.

The best i can describe it is with an analogy
Imagine you stuff this emotion in a specific spot
Like you would stuff some garbage in a dump.
And then you stuff more, and more, and more
over time it becomes a festering cesspool of dis-ease.

In physical terms... i guess it is still in the real of metaphysical
this stuffing of emotions starts to create a black cloud on the emotional layer of your body.
Continued it grows denser and denser until it affects the layers near it, and then the physical layer of the body.

Get the book "Hands of Light" by Barbara Brennen to see the drawings she had made of what she sees.

What i have experienced is that if you can get the patient to stop stuffing these emotions, to start working on these emotions, then almost anything will cure the cancer.
And the opposite is true. If they do not heal the emotion, then nothing will cure the cancer.

Have you also looked into cancer spontaneously healing?
Here today, gone tomorrow.

... and in some cases here today, gone tomorrow, back the next day.
