With 80,000 people awaiting transplants each year, it is no wonder some of them weary of waiting and decide to take action. We talk with a medical anthropologist who has found a thriving traffic in organs from living donors in a number of poor countries. This raises questions about health and ethics: should people be allowed to sell a kidney? What are the consequences for the donor and for the recipient? We discuss these matters with a transplant surgeon and take your questions. Guests: Nancy Scheper-Hughes, PhD, University of California, Berkeley Thomas Diflo, MD, Director of kidney transplantation, NYU Medical Center in New York of renal transplantation at the NYU Medical Center in New York
