OUR THINKING about the cause of cancer has gone in large, slow cycles. At about the turn of the century, the German biologist Boveri first suggested that abnormalities of the chromosomes were the key to cancer. But at about the same time, the Rous chicken sarcoma virus was discovered, and later the rabbit papilloma virus. Subsequently in the 1930s and 1940s, chemical carcinogens, and then in the 1950s and 1960s tumor viruses again, were the candidates discussed most frequently. The popularity of viruses declined abruptly a few years ago, to be replaced once more with the belief that environmental agents are the cause of common tumors in humans. However, within recent months attention has focused again on oncogenes (genes in normal cells that play a role in the production of tumors) contained in certain animal tumor viruses aiad in both animal and human tissues and tumors. With modern methods in molecular genetics, including gene cloning, transfer, and sequencing, current research suggests close similarities, or even identities, between specific genes in these animal tumor viruses and in some human tumors. In addition, clinicians have known for many years that an individual's genes contribute to the likelihood that he or
