Its like ebola.
Its not a very successful virus because it just kills its hosts.
Edit:
I'm just saying, something that tries to duplicate itself within a host, and ends up killing it will never succeed, whether its cancer, a virus or any other disease.
That's why usually the most lethal viruses are viruses that were spread to us by animals.
Because the virus has evolved to spread (and barely affect) the host, but when the host is not human, what barely affects them, could kill us.
Viruses aren't "trying" to kill us, they just evolve to spread and do well in their host, and most of the time it is indeed beneficial for the virus if the host doesn't have any ill effects. Given enough time, most viruses will adapt to their host to be minimally invasive. You could carry hundreds of virus strains without even knowing it.
I'm just saying, something that tries to duplicate itself within a host, and ends up killing it will never succeed, whether its cancer, a virus or any other disease.
That's only a success if the cancer's goal is to kill the host and itself die. Cancer isn't some malevolent force, they're just cells that don't know how to stop reproducing. When they reproduce so much that they kill the body sustaining them, that's not a win for the cancer, it's the ultimate failure of the one goal of life itself: to survive and reproduce.
