This "doctor" is a well-known (among actual cancer doctors) quack. Like any quack, he is a psychopathic con man who preys on people's desperation to give them false hope and relieve them of their money.
Here is a blog where a legitimate cancer doctor comments (a lot) about quack Burzynski. There is no scientific evidence to support Burzynski's claims. He is scum, the lowest of the low, who richly deserves his "long history of being beat up by the feds" and much more.
When talking about posts such as those here on FR or any other online forum written by regular Joes and Janes, typos and mispelling and grammatical errors pretty much deserve a universal pass because this is a strictly amateur/hobby forum. But when an ostensibly "professional" source is so cavalier as to (wittingly or unwittingly) spit in the face of correct English as much as this Med Guru, it tells me that the source is either woefully ignorant or extremely arrogant, or most likely both. That's not to say that the info he presents is correct or wrong, but it IS to say that readers should understand something about the mindset of where that info is coming from.
