Growth, as a self-organized system (as it is in cancer), when it is unbounded, eventually kills the host organism. The bounds are the check on growth, such as ["OTOH .... we could cooperate with each other and work as a collective and try to ensure the survival of the species"] but, it requires the administration of treatment and, almost always, against the desire of the host organism.
It can work. But we can't wait for it to happen on its own. By then it'll be too late.
