The Pathogenic Factors of Brain Tumors —— Molecular Biological Study of Tumors
At present, it is considered that the factors that induce tumors are genetic factors, physical factors, chemical factors and carcinogenic viruses.
The research of tumor molecular biology shows that there are two kinds of genes closely related to the occurrence and development of brain tumors. One is tumor gene, and the other is anti-tumor gene. The activation and over-expression of anti-tumor genes induce the formation of tumors, and the existence and expression of anti-tumor genes help to inhibit the occurrence of tumors.
Tumor genes can exist in normal cells and do not express tumor characteristics. When these cells are exposed to tumorigenic factors, such as virus, chemical tumorigenesis and radiation, the tumor genes in the cells are activated, the phenotype of the cells changes, the tumor characteristics are expressed, and these cells expand rapidly, thus forming real tumor entities.
Pathogenic factors of brain tumor-Chinese medicine theory In China, Chinese medicine believes that the etiology of brain tumor is internal quality factors or susceptibility factors, and external inducing factors or contributing factors, but these two factors are not pathogenic factors.
Brain tumor belongs to the category of "headache" and "head wind" The main causes are kidney deficiency, dystrophy of marrow and sea, homology of liver and kidney, deficiency of both kidney and liver, internal movement of liver wind, obstruction of collaterals by phlegm, obstruction of collaterals by brain collaterals, stagnation of blood gas, and "the head is the meeting of all yang", which is the least tolerant of evil spirits.
1, away from dangerous cancer-promoting factors
What are the factors that promote cancer? Unhealthy diets such as barbecue, deep frying and high salt are hotbeds of cancer. Scientific research shows that many cancers can be prevented before they are formed. Dr Higginson's research from 65438 to 0969 concluded that 90% of malignant tumors were caused by environmental factors. "Environmental factors" and "lifestyle" refer to the air we breathe, the water we drink, the food we choose to make, the habits of activities and social relations. A report from 65438-0988 in the United States made a detailed comparison of international malignant tumors, and suggested that about 80% of malignant tumors could be prevented by simple lifestyle changes.
2, from the aspects of reasonable diet, exercise and emotional control, improve the immunity of the body.
A reasonable diet can prevent not only cancer, but also other diseases. Studies have shown that vitamin A plays an important role in reducing cancer risk. Vitamin A supports normal mucosa and vision, and it directly or indirectly participates in most tissue functions of the body. Vitamin A exists in animal tissues such as liver, whole eggs, whole milk, etc. It exists in the form of β -carotene and carotenoid in plants and can be converted into vitamin A in human body. Excessive intake of vitamin A will cause adverse reactions, but β -carotene and carotenoids will not.
We know the causes of brain tumors and that brain tumors can be prevented. The key is to start from the bits and pieces of life. Adhere to a healthy lifestyle, exercise regularly and have a good mood. Rewen: Gamma knife surgery to treat optic nerve tumors and restore vision.
