What causes brain cancer

What causes brain cancer? As our living environment becomes worse and worse, the incidence of brain cancer is also increasing year by year. It can be said that prevention of brain cancer is urgent. However, before we prevent it, we need to know what are the factors that cause brain cancer so that we can try to skip these carcinogenic factors to prevent cancer. This is very necessary.

Physical factors: Today is an era of advanced technology. There are more and more electronic products for children, such as iPads, mobile phones, and electronic learning machines. But while we let children enjoy these things, they are also quietly "harming" children. Because radiation sources are also a kind of environmental pollution. And you should know that the onset of some brain tumors may be related to the loss or mutation of specific genes, and radiation is one of the sources of gene mutation.
Chemical factors: Animal experiments have shown that a variety of chemicals are the cause of brain tumors (various gliomas, meningiomas, neoplasms, epithelial cancers, pituitary adenomas, etc.). Common ones include anthracene compounds, such as methylcholanthracene, diphenylanthracene, benzopyrene, etc., and N-nitrite compounds, such as nitrosopiperidine, dinitrosopiperazine, methylnitrosourea, etc.
Genetic factors: They play an important role in the onset of some brain tumors. Human gene defects or mutations can form intracranial tumors. Neurofibromatosis is a typical hereditary nervous system tumor, and about half of the patients have a family history of the disease.
