I figured there was a good reason the FDA pulled their approval.
I didn't read the wiki article, but I've read quite a lot about them. I don't know if you can prove anything either way. They claim the FDA does't want one clinic to hold the patent and for all the research funds to go to them, and therefore the FDA has been against them since day 1. The FDA is heavily influenced and $$$ by the pharmaceutical companies. The FDA claims it's not safe or whatever else the pharmaceutical guys convince them of.
OTOH, I know someone who wanted to use antineoplastins for his father, and he tried getting in touch with some of the people who wrote testimonials and were on bursynski's videos, but he couldn't get thru to anyone.
I don't think you can know either way for certain. This is a multibilllion dollar industry, and like other government offices, you can't say billions of dollars doesn't affect their decisions.
But what the heck? The doctor said there's nothing that can be done. What could possibly go wrong with using antineoplastins? worst case, he dies c"v. The doctors gave up anyways. There can only come good from this. Why does the FDA care?
