Briefly describe what is glioma

Because the living environment in today's society is getting worse and worse, the incidence of various tumor diseases has been increasing in recent years. Glioma, which is common in clinical medicine, is a type of highly harmful and high-incidence malignant tumor that can directly cause patients to lose multiple functions, and produce movement disorders, visual disorders, and language disorders. These hazards make many patients feel very scared. What exactly is glioma? Today I will give you a brief introduction to what glioma is.

Glioma, also known as glioma, is a tumor that occurs in the neuroectoderm. There are two types of tumors that occur in the neuroectoderm: one is formed by mesenchymal cells, called gliomas; the other is formed by parenchymal cells, called neuronal tumors. Glioma accounts for 40-50% of brain tumors and is the most common intracranial malignant tumor.

According to pathology, it can be divided into astrocytoma, medulloblastoma, glioblastoma multiforme, ependymoma, oligodendroblastoma, etc.

1. Astrocytoma: It is the most common type of glioma, accounting for about 40%.

2. Medulloblastoma: It is a highly malignant tumor that is common in children aged 2-10 years old. The youngest cases can be seen in children as young as a few months old. Most of them originate from the cerebellar vermis and grow toward the fourth ventricle and the cerebellar hemispheres of the medulla oblongata. Because it blocks the cerebrospinal fluid circulation channel, it is often accompanied by hydrocephalus when discovered.

3. Oligodendroglioma: It is a low-grade malignant tumor, which is relatively benign. Many people also call it a benign tumor. It grows slowly, and calcified plaques can often be seen in the tumor.

4. Ependymoma: It is also a type of glioma, and its principles are basically the same as those of astrocytoma.

Most gliomas develop slowly, and the time from the onset of symptoms to seeking medical treatment is generally weeks to months, and a few can take years. The history of highly malignant tumors and posterior cranial fossa tumors is shorter, while the history of more benign tumors or tumors located in quiet areas is longer. If the tumor bleeds or cysts, the symptoms will suddenly worsen, and even have a course similar to cerebrovascular disease.

Most gliomas develop slowly, and the time from the onset of symptoms to the time of seeking medical treatment is generally weeks to months, and a few can take several years. The history of highly malignant tumors and posterior cranial fossa tumors is shorter, while the history of more benign tumors or tumors located in quiet areas is longer.

Therefore, gliomas are relatively malignant, and conventional treatments are not very effective for gliomas. Biological therapy, as a new anti-tumor treatment method, has brought new breakthroughs in treatment methods to the majority of cancer patients.
