Nature will just find something else to kill us. Everybody dies of something. Fix or eliminate one cause of death and something else becomes prevalent. Look at all the basic illness that killed high numbers of people that we now take medicines from the chemist without any second thought.
I'm not saying cancer is good or shouldn't be cured, but death is a fact of life (pardon the pun) and nature will always find something to replace a disease or creature or plant that becomes extinct.
Just as you have evolution of plants, animals and humans, you also will have evolution of diseases. Eliminate 99% of household germs and you get super viruses.
Unfortunately, nature will always find different ways to kill us.
