Evolution is Not a Scientific concept - i.e. not verifiable as it lacks a clear, testable definition. If and only when this will ever be resolved, we will be able to compare Cancer to Evolution and evaluate a possible match.
Until then, a simple observation is that Cancer kills itself by killing the host (if we even want to go as far as assigning a self to Cancer). Transmission in a few cases is due to the incidental and preexisting behavior of the host which has nothing to do with the Cancer itself. If Cancer had modified the behavior of the host, then the resemblance might be somewhat more believable.
