Hazards of cancer, cancer is a malignant tumor of the study, said all parts of the body by normal cells in a variety of changes under the action of carcinogenic factors, from its vigorous growth, the growth was relatively open-ended, and the body's normal metabolic function of lack of coordination seriously affected the normal function of various body organs, damage the normal structure, is the serious threat to human health and life of the disease.
Cancer can occur in almost any part of the body. Medicine in accordance with the organization from different sources give different names.
