I should have said entirely metabolic. You can make the case that cancer is a genomic disease, cancer is a disease of cell signalling, cancer is a disease of impaired repair mechanisms, etc etc.
Delving deeper, he states it is a metabolic disease based on insufficient amygdalin.
Cancer ****s everything up, which is the best part about this guys argument. He's taking a multifaceted disease and making it one dimensional.
Side Note: Is Jesus okay with that finger thing, or are you on the fast track to hell as well?
