A report on tumorigenic cancer cells -- cells that generate tumors -- suggests that nongenetic factors could play a much more significant role in the growth or diminution of tumors than previously thought. A research team injected cells from human tumors into genetically similar mice and found that the tumors still affected the mice in a variety of ways. "There's a huge ... belief that if we sequence more tumors and identify more mutations ... that we are going to be able to effect more cancer cures," cancer biologist John Dick said. "We should not be putting our eggs exclusively in the genetics basket," he added.
