My guest is Dr. David Fajgenbaum, MD, professor of translational medicine and human genetics at the University of Pennsylvania. He explains how, unbeknownst to most doctors, many approved medications can successfully treat or even cure diseases other than the ones they are typically used to treat. He shares his story of escaping death from Castleman’s disease by discovering a life-saving treatment using repurposed drugs that were approved for other purposes. Our conversation explores how researchers, physicians, and you—the general public—can explore novel treatments and cures to conditions the medical profession has deemed untreatable, including cancers. We also discuss the crucial role of mindset in battling diseases and the lesser-known use of compounds to promote health and longevity.
