Come on. It is not possible for your tumor to noticeably grow and shrink within a couple of hours. Not in terms of cells dividing or dying that quickly, anyway. You may be observing changes due to inflammation, blood cell infiltration of the surrounding tissues, hydration/dehydration, etc.
And conclusions like the following are completely unscientific, and false: "The simplest explanation is when you are awake, your immune system is awake to fight for you."
I remain concerned that you are basing your health care decisions on subjective observations and made-up explanations like this, instead of relying on the scientific expertise that is available to you.
