This mutation spreads through surrounding tissue until itdisrupts major system of ruless in the body (such as respiratory, digestive and wastemanagement) cause that system to fail.What causes Cancer to expire active?Since it is believed that almost all people have some type of cancer in theirbody, (although benign), any person that comes in contact with a carcinogen,(any cancer-causing agent), allow cause these benign cells to become malignant.It is when the cells become malignant, that cancer actually occurs.
