U.S. War on Cancer
Cancer has been a difficult disease to cure. In 1971 the U.S. passed the National Cancer Act which was the beginning of the "war on cancer", a popular phrase of the time. If we could achieve such a technological feat as putting men on the moon in such a short period of time , surely a well funded program will cure cancer as quickly. 45 years later we are still at war. While progress has been made, cancer is still a major killer. Immunotherapy is developing to be a major weapon not only to treat cancer, but to cure it.
