And what we’re saying is not just that this is cells gone wrong this is cells reverting to the way they used to be a billion years ago. . . . If that cooperative arrangement breaks down, cancer results. If there’s a skin cell, for example, it can’t just decide to replicate it has to wait for a signal, a message to tell it to do so. . . . And so now in our bodies, all of this is very tightly controlled.
