Cancer is an umbrella term for aggressive cell growth, there will never be a "cure" but slowly they will find ways for the countless types to be halted or slowed down..
Its depressing but it's the truth
To the people with the conspiratorial mind-sets, the universe is based on chance and therefor there are chances of anything and they are higher or lower.. some get lucky some don't... the government or big pharmaceutical companies don't want children to die young of cancer.. NO ONE wants that.. not even the worst people.
