This week, Point of Inquiry welcomes David Gorski, MD, PhD: cancer researcher, surgeon, and managing editor of the Science-Based Medicine blog, aka "Orac" of Respectful Insolence.    

Gorski and Beyerstein discuss a pair of exposés of cancer quack Stanislaw Burzynski in the March/April issue of the Skeptical Inquirer, one by Gorski and one by skeptical activist Robert Blaskiewicz. 

Gorski explains why Burzynski's urine-derived antineoplaston therapy is worthless; how the doctor strong-armed the FDA into letting him peddle these expensive and potentially dangerous drugs for over 30 years; and how the treatment may have killed a little girl. Gorski also discusses Blaskiewicz's report on skeptical activists who banded together online to warn the public about Burzynski's quackery and push back against his attempts to silence his critics.
