What is cancer?

That is, malignant tumor, as opposed to benign tumor. Tumor refers to a local mass formed by abnormal proliferation of cells in local tissues under the action of various tumorigenic factors. Benign tumors are easy to clean up, generally do not metastasize or recur, and only have squeezing and blocking effects on organs and tissues. However, malignant tumors can also destroy the structure and function of tissues and organs, causing necrosis, bleeding and infection, and patients may eventually die of organ failure.

The basic unit of cancer lesions is cancer cells. After aging and death, human cells will be replaced by new cells to maintain their functions. It can be seen that most cells in the human body can proliferate, but this proliferation is limited, and the proliferation of cancer cells is endless, which makes the nutrients in the patient's body be consumed in large quantities. At the same time, cancer cells can also release a variety of toxins, causing a series of symptoms. If not found and treated in time, it can also be transferred to various parts of the body for growth and reproduction, which will eventually lead to emaciation, weakness, anemia, loss of appetite, fever and organ dysfunction.

Cancer can occur in almost every part of the human body. Originally, the biological machine of human body runs seamlessly, but cancer has changed this situation, and its task is to destroy it. If it continues, it will drag down the human body. However, unlike viruses, tumors are not intruders in vitro, and their components are the same as normal tissues, so the body cannot recognize them.

Causes of cancer:

At present, we can't know exactly the mechanism of cancer cell growth, that is, the law of gene mutation. However, we know some factors that lead to gene mutation, such as environmental factors: cigarettes, toxic chemical gases, polluted water and food. Physical factors: radiation, ultraviolet rays, food overheating, etc. Mental factors: long-term anxiety, tension, mental depression, depression, etc. Endocrine and metabolism: endocrine disorders and metabolism of chemicals in the body may cause cancer; Heredity is sometimes the cause of cancer. People who have been exposed to carcinogens for a long time are more likely to suffer from pain. As far as we know, there are more than one hundred kinds of cancer. They have different causes and propagation speeds. However, environmental factors and dietary factors are still the two main causes of cancer.

Some cancers can be treated with chemotherapy, and the effect is remarkable. The side effects of chemotherapy are hair loss, excessive vomiting, fatigue, weakness, infertility and kidney and heart damage. Some nutritional supplements and health-care Chinese medicines can help the body avoid the damage caused by this treatment.

Some people call cancer the immune system disease terminator, because it really affects every part of the immune system. Whether the pain can be cured is related to many factors, including the type of cancer, the time of diagnosis, the patient's medical history, lifestyle, heredity and attitude.

The symptoms of cancer vary according to the infected site, but generally there will be symptoms of burnout, weakness, depression, weight loss, pain and loss of appetite. It is considered that13 of cancer cases are related to diet, so healthy diet is the best way to prevent cancer, and avoiding environmental pollution is the fundamental way to avoid cancer.
