Slate star codex kind of speculates [1] that it might have something to do with scale, ie -- in order to keep growing in a creature that large, the cancer cells need to coordinate among themselves and specialize to a degree that is not needed at smaller scale. In other words, before the cancer can grow large enough to threaten the host, "the cancer gets cancer."
