A brief discussion on the hazards of glioma

Glioma is a common disease in the brain. It is a tumor of the neuroectoderm. It is difficult for most people to accept tumors. After all, it is mainly because there is no better effect in its treatment. This type of tumor seriously affects the daily behavior of various parts of the human body. Let's talk about the hazards of glioma.

There are many ways to classify gliomas, and clinicians often use the Kernohan classification, which is relatively simple. Among all types of gliomas, astrocytomas are the most common, followed by glioblastomas, followed by medulloblastomas, ependymomas, oligodendrogliomas, pinealomas, mixed gliomas, choroid plexus papilloma, unclassified gliomas, and neuronal tumors. Each type of glioma has a different predilection site. For example, astrocytomas are more common in the cerebral hemispheres in adults, and more common in the cerebellum in children; glioblastomas almost always occur in the cerebral hemispheres; medulloblastomas occur in the cerebellar vermis; ependymomas are more common in the fourth ventricle; and oligodendrogliomas mostly occur in the cerebral hemispheres.

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.
