This week's guest is Dr. Paul Billings, a board-certified internist, renowned researcher, and clinical geneticist. Dr. Billings and Dr. Juneja talk about new methods of early detection of cancer and dive into Dr. Billings's recent research endeavor on exosomes and how they function to identify potentially cancerous cells from a single blood draw, even before symptoms occur. This revolutionary technology aims to redefine cancer screening as we know it.
