Each year the news division hosts the WNYC Health Convening with support from the Alfred P. Sloan Foundation as an opportunity for healthcare experts and practitioners to inform WNYC's health reporting. This year, as part of our centennial series "100 Years of 100 Things," Paul Goldberg, editor and publisher of The Cancer Letter and co-editor of The Cancer History Project, discusses the century of cancer treatment advancements and how the U.S. government played a major part in funding the science for treatment, early detection and prevention.
