How do you get glioma

Tumor is a disease that is very difficult to treat. Glioma is a difficult disease that often occurs in the brain. It is a tumor of the neuroectoderm. Because this type of tumor occurs in the brain, it seriously affects the daily behavior of various parts of the human body. Let us understand how glioma is caused.

Most gliomas develop slowly, and the time from the onset of symptoms to medical treatment is generally weeks to months, and a few can take several years. Highly malignant tumors and posterior cranial fossa tumors have a shorter medical history, while more benign tumors or tumors located in quiet areas have a longer medical history. If the tumor bleeds or cysts, the symptoms will suddenly worsen, and may even have a course similar to cerebrovascular disease. The clinical symptoms of gliomas can be divided into two aspects. One is the symptoms of increased intracranial pressure, such as headache, vomiting, decreased vision, diplopia, mental symptoms, etc.; the other is the focal symptoms caused by tumor compression, infiltration, and destruction of brain tissue, which can manifest as irritation symptoms such as localized epilepsy in the early stage and neurological dysfunction symptoms such as paralysis in the later stage.

Gliomas are more common in men, especially glioblastoma multiforme and medulloblastoma, which are significantly more common in men than in women. All types of glioblastoma are more common in middle-aged people, ependymoma is more common in children and young people, and medulloblastoma almost always occurs in children. The location of glioma is also related to age. For example, cerebral astrocytoma and glioblastoma are more common in adults, while cerebellar glioma (astrocytoma, medulloblastoma, ependymoma) is more common in children.

Among all types of gliomas, astrocytoma is the most common, followed by glioblastoma, followed by medulloblastoma, ependymoma, oligodendroglioma, pinealoma, mixed glioma, choroid plexus papilloma, unclassified glioma and neuronal tumor. Each type of glioma has a different predilection site. For example, astrocytoma is more common in the cerebral hemisphere in adults and more common in the cerebellum in children; glioblastoma almost always occurs in the cerebral hemisphere; medulloblastoma occurs in the cerebellar vermis; ependymoma is more common in the fourth ventricle; oligodendroglioma mostly occurs in the cerebral hemisphere.
