Here's what I said on page 2:
"Alright, that one gave it away. This person is just trying to get a rise out of everyone."
I think the subsequent pages smiled kindly on that view.

You should notice that it treats the cancer by...wait for it...using "the body's immune system to fight cancer."
The process, to be quick, teaches white blood cells to attack the cancer. Notice that's a causal description.
Now one more time: what happens to the immune system under your treatment? Do you teach the white blood cells to attack the appropriate pathogen? Do you increase the white blood cells a person produces? What is happening on the cellular level?
Or do you grab someone's arm and let the details fall where they may?
