^I think it's more because balance within the body is shifting to the genes of the foreign species inhabiting the human body. It can coexist, but it can't adapt or live on the genes of the foreign species alone. Since human genes can't heal that fast, the Rc cells take over to heal and prevent their host from dying, making it so that the Rc cells and ghouls genes slowly spread across the complete body & the less of the original genes are left. The host will die from an overload of foreign tissue.

Is my guess...
