It's really not that tough to get a certificate to hand on your wall, a medical bible, and a white smock. What differentiates a doctor from a healer is independent, intelligent reasoning.
Patient, you have cancer (fill in your disease) because you are abusing yourself to the point that your immune system is severely depressed and can no longer do its job...so we'll just pump you up with more toxic poison, cut out the offending parts and fry it to smithereens because this is the protocol in our medical bible.
Now, does this sound like independent, intelligent reasoning?? LOL!!
