Editorial
Light Is Cancer’s Latest Foe
The race to cure a killer disease first got federal support back in 1937, when US President Franklin D. Roosevelt signed the National Cancer Institute (NCI) Act. On Jan. 3, 1938, the National Advisory Cancer Council recommended approval of the first cancer research fellowships. Decades of research, both privately and federally funded, have certainly broadened our understanding of this disease...
