PBS News Weekend

Season 3, Episode 1 of 86

On Saturday, NewsHour Weekend examines the science of using dogs to detect cancer. For the past few decades, researchers have been exploring the possibility that cancer, possibly created by the growth of tumors, actually has a particular odor -- and dogs can pick up on that smell. Some doctors believe this area of research may lead to more efficient screening methods and cancer treatment procedures. That, and the weekend's news, online and on-air.
