This video segment adapted from NOVA, features cancer researcher Dr. Judah Folkman and describes his approach to proving a new idea he had about how tumors grow inside the body. His idea focuses on angiogenesis, the formation of new blood vessels. Dr. Folkman designed experiments to test his central hypothesis and thus prove the support mechanism behind tumors.
This video is available in both English and Spanish audio, along with corresponding closed captions.
