Yeah, but those convos don't always go very well (ask me how I know...).

Also I think that's almost always true - certainly for the kinds of cancers that would show up on a PET scan - but that some cancers apparently use diff substrates for growth. (? I went deep into this ages ago, and don't remember the details so I could be/would love to be wrong about that.)

In any case everything improves when you improve your metabolic health!
