Researchers say the claim that fracking has been linked to increased cancer rates in Texas is simply wrong. Fox, an Oscar-nominated filmmaker who uses the claim in a new film, declined to acknowledge the error when told of researchers who say he's doing a disservice to people with cancer by misrepresenting health data.
