Child Cancer Patient Petitions For Brain Tumor Treatment Not Yet Approved By The FDA (VIDEO)

Last Thanksgiving, 12-year-old McKenzie Lowe was diagnosed with an inoperable brain tumor. Her family is petitioning New Hampshire's governor to allow McKenzie to undergo Antineoplastons therapy, a treatment not approved by the FDA. The FDA has allowed 471 "compassionate use" exemptions to date, and McKenzie's grandfather, Frank LaFountain, hopes she'll be next in line.

"We've talked to survivors of this drug, who had the same condition McKenzie has," he told HuffPost Live host Nancy Redd. "People say there aren't any, but we know them. We've talked to them, and that's what makes us so passionate about getting her this particular drug."

The family has received support from local politicians, but does not plan to stop until McKenzie has approval. "We'll just keep going across the country until we get them all on board and we get this changed so she can receive this drug," LaFountain said.
