how you try to treat uncurable agressive cancers before you put the body in strong chemical s**ts (very low chances)
You eat just vegatables (like beetroot) and drink water with a bit of salt. The only hope
If you eat carbohydrates / proteins the cancer have power to become bigger...
the body to protect the brain and heart, "eat" first the fat, muscles and or unecessary soft tissues
the problem is when you have cancer in brain...but still if you are full of carbohydrates and protein it will become bigger.
The cancer is a kinda creature (living cells) which wants to live..like all cells in your body
acciddently some scars can also be "eaten"
but it's tricky thing, reserved for life threating conditions
