Of cancer we,ve know that it could well be present in so many environmental factors.And thus
exposure to some metals and thus exposure to some waste.So that.
Risk of getting cancer every time an environmental factor x of the amount of danger 6 out of 10.
x = v + f x z / h
Where:
v = environment as the exposure of the product in the air.
f = Possibility of contact with water.
z = Genetic predisposition to environmental factors.
h = body resistance.
