Cancer, medically known as: malignant neoplasm

World-renowned medical scientists believed that cancer causes are: the body in the environmental pollution, chemical pollution (chemical toxins), ionizing radiation, free radical toxins, micro-organisms (bacteria, fungi, viruses, etc.) and their metabolic toxins, genetic features, endocrine imbalance, immune dysfunction, and so a variety of carcinogenic substances, under the action of carcinogenic factors, lead to physical results of cancerous and normal cells that often appears as: local tissue cells formed by abnormal proliferation of local mass. Cancer is the body's normal cells in many reasons, the multi-stage and multiple mutations caused by a large class of diseases.

Cancer of the features are: unlimited, indefinite proliferation, so that patients are a large number of nutrients the body consumption; cancer cells release a variety of toxins, so that the human body produce a series of symptoms; cancer cells throughout the body can also be transferred to the growth and reproduction of , leading to body weight loss, weakness, anemia, loss of appetite, fever and severe organ dysfunction and so forth. As opposed to a benign tumor, benign tumors are easy to clean, generally do not transfer, no recurrence of the organs, tissues and blocking only the squeezing effect, but the cancer (malignant tumor) can damage tissues, organs of the structure and function of has caused hemorrhagic necrosis infection, the patient eventually died due to organ failure.

Scientists pointed out: the fragile immune function is a key factor leading to cancer.
Today's world, many clinicians and patients for surgery, radiotherapy and chemotherapy to treat cancer and other means of over-reliance on too much superstition, there is a great misunderstanding.
Cancer is a systemic disease of part performance. The pathological nature of the cancer is a systemic disease, not just the performance of local tumor.
