Kim, also FYI, the FDA has nothing to do with the actual research, it is only the approver of a drug or treatment that has already gone through research and clinical trials. (See this link that explains clinical trials http://www.oralcancerfoundation.org/facts/clinical_trials.htm) I am in a clinical trial at MD Anderson, and I can bet that if some of the doctors there or at other cancer research centers thought that this treatment had efficacy, they would be studying it (and perhaps are already doing research in related areas)
