How exactly does cancer occur? What exactly is cancer

Cancer occurs in this way: cancer is a disease produced by the combined action of the genetic environment, and most cancers have been proven to be caused by exogenous carcinogenic factors and the body's own genetic aging, immune metabolism and other factors.

Some people get cancer because of environmental factors. There are a lot of toxic and harmful substances in the surrounding environment, and it is easy to get cancer if you work or live in this environment for a long time. For example, asbestos dust in the working environment of workers working in asbestos factories can cause very serious damage to people's lung health, and at least 90,000 people die of lung cancer caused by asbestos exposure worldwide every year.

External living environment, such as some work environments containing harmful substances, low autoimmunity, bad living habits, poor eating habits, and usually suppressed emotions are caused by a combination of factors.

Staying up late for a long time and eating irregularly, the small diseases of the body expand into big diseases, and then form cancer, which is very difficult.

The reason why cancer refers to all malignant tumors is that normal cells are mutated into cancer cells under the action of physical, chemical, viral and other carcinogenic factors. Cancer cells are transformed from normal cells and are the source of cancer. Unlike normal cells, cancer cells have three characteristics: indefinite proliferation, transformation, and easy metastasis.

It can proliferate indefinitely and destroy normal cells and tissues, and can also locally invade surrounding normal tissues, and even pass through the circulatory system or lymphatic system in the body and transfer to other parts of the body. Cancer, together with cardiovascular diseases, accidents and accidents, constitutes the three major causes of death in the world today, and is one of the major diseases that seriously affect human health and threaten human life. It grows rapidly, can invade surrounding tissues, and can also spread to the surrounding area, which is powerful and destructive.

In addition to the symptoms of obstruction and compression on the body, it may also affect the normal and functional function of genetic organs, causing people's death.

Cancer is a group of cells that grow wildly, because of the DNA mutation of the cells in the body, or changes in the internal environment and changes in the external environment, resulting in sudden and uncontrollable growth of cells. And these cells are aggressive and run around the body.

Cancer cells are caused by DNA chain gene mutations, and these protein abnormalities lead to protein destruction mutations and DNA changes, which then lead to protein changes, which are the cells that are produced, and the cells grow wildly, and the internal environment changes to a systemic cachexia state.

Cancer can cause pain in patients, mass lesions can compress pain, cause local lumps, cause discomfort to patients, and most importantly, fatal. The cachexia state affects the normal function of absorption, affects all normal functions, and leads to the inability to live, survive, and finally the patient dies of cancer.

Loss resistance. It's a disease. Cancer repair. into cancer. Simple. Get complicated. I want to cure cancer. Vain wax.

The occurrence of cancer may be caused by biological factors, physical factors, chemical carcinogenic factors, abnormal immune function, endocrine disorders, insufficient nutritional supplementation, genetic factors, etc.

The causes of cancer are very complex. There are factors of their own, as well as environmental factors. For example, smoking can also cause lung cancer. Or if you have hepatitis B virus and hepatitis C virus, you can also develop liver cancer.

I think the main way to cause cancer is that people don't pay attention to the principle of restraint in what they eat in their daily diet, and it is caused by eating too many chemicals.

Physical carcinogenic factors mainly include ionizing radiation, ultraviolet radiation and some mineral fibers. Biological factors are viruses, bacteria, parasites, etc.
