I have to respectfully disagree with this approach. Since this doctor was taught "medicine" inside the Rockefeller system, he seems not to be able to think outside of this system, which is simply wrong and has more of a religion than science.
As a matter of fact, "cancer" is not even a "disease", but a natural biological regulation process. So there are no "carcinogenic" substances, since the process called "cancer" by conventional medicine has a meaningful biological function. I invite you to have a look at the (Germanic) New Medicine, which is a truly scientific system based on biological laws and explains all the things conventional medicine does not understand. And more important, anyone can check and prove this for himself.

These are good places to start:
