At present, the incidence of brain tumors is getting higher and higher, so it is necessary to have a certain understanding of brain tumors. So, what are the causes of brain tumors? 1. Physical factors Several years after radiotherapy for brain tumors, the occurrence of other tumors in the irradiated area is one of the causes of brain tumors. Animal experiments have found that radiation can cause tissue metastasis (cancer). The mechanism is that radiation causes oncogene mutations in intracranial fibroblasts or meningeal endothelial cells, causing cell cancer. 2. Chemical factors Animal experiments have confirmed that a variety of chemicals are the causes of brain tumors (various gliomas, meningiomas, sarcomas, epithelial cancers, pituitary adenomas, etc.), common ones include anthracene compounds, such as methylcholanthracene, diphenylanthracene, benzopyrene, etc. 3. Congenital factors: During embryonic development, primitive cells or tissues remain ectopically in the cranial cavity. Under certain conditions, they have the ability to differentiate and proliferate, which can develop into the cause of congenital brain tumors. These tumors grow slowly and are mostly benign. Common ones include craniopharyngioma, lipoma, and colloid cyst. 4. Genetic factors: Human gene defects or mutations can cause brain tumors. Neurofibromatosis is the most typical representative of the inheritance of nervous system tumors. It is an autosomal dominant hereditary tumor, and about half of the patients have a family history of the disease. The above are some of the causes that may lead to brain tumors. I hope everyone has a clear understanding of brain tumors, especially the causes of brain tumors. Brain tumor: http://www..com.cn/zhongliu/na/nzl.html |
