when doctor talk about cancer, they only say how the good cell change into bad cell, the bad cell change into cancer....
they never tell you, you are what you eat, forexample they never tell you eating mcdonald for a whole year will cause cancer, and they never tell you, you should sleep before 20:00 every night, and they never tell you they only want your $$$ not to make you healthy, this is why most of them buy westen departments, and feeding branded dogs.
