The Three Stages of Cancer
Cancer is a multi-stage disease. First, a cell must be initiated by a carcinogen such as a chemical or a virus. The DNA genetic material is modified and becomes capable of producing abnormal cells. During the promotion phase and under favorable conditions, these initiated cells will multiply because normal growth restraints have been removed. This phase can last from a few months to more than 20 years. In the final stage, progression, cancer cells multiply rapidly, disrupting body functions and leading to death.
