The War on Cancer refers to the effort to find a cure for cancer by increased research to improve the understanding of cancer biology and the development of more effective cancer treatments, such as targeted drug therapies. The aim of such efforts is to eradicate cancer as a major cause of death. The signing of the National Cancer Act of 1971 by then U.S. President Richard Nixon is generally viewed as the beginning of the war on cancer, though it was not described as a "war" in the legislation itself.
