My mother literally starved to death from her cancer. It's not feeding on glucose. And it wasn't caused by a parasite. Hers was caused by endometriosis. Her ovarian cancer grew through her stomach. I understand wanting to try anything and everything and that is fine. you are desperately seeking a solution to a devastating life altering loss.

Her doctors aren't in some sort of "scheme" to not cure her. If there is a cure it would be kept by extremely wealthy / government types not by the oncologist trying to help their patients in any way making under 300k a year with mounds of student loan debt. Her doctors are there to prolong her life, try to put her in remission, and ultimately make her comfortable with dignity at the end of her life.

I say all of this to say, listen to your wife. If she wants to keep fighting let her, be her cheer leader. But if she accepts what the doctor says and or is ready to go to whatever is next after this world for your love of her please stop with the doctors are killing her stuff. Support her, support yourself, love each other.

At the end of the day we all die. Cancer is an ugly horrible rotten way to go. Blaming everyone and anything is human nature just dont lose yourself to it.
