Astrocytoma Malignant

Astrocyoma maligna is a malignant tumor arising from astroglial cells in the brain. Malignant brain tumors are among the most dangerous types of cancer and can lead to serious consequences for human health. Today we will talk about what astrocytoma is, why it occurs, what symptoms and treatment exist.

What is astrocytic? Astrocytes are glial cells that make up about 20% of the total mass of the brain and spinal cord. They ensure the maintenance of the shape of neurons, their nutrition and protection from infections. Astrocytes are also key participants in the repair process, that is, the restoration of tissue after injury.

A malignant brain tumor, astrocytoma, is a cancer that arises from astrocytes. The exact origin and mechanism of development of astrocytoma are still unknown.

Causes of cancer Among the various factors influencing the risk of developing malignant tumors, we should highlight

So, an astrocytome or glioma is a tumor that arises from astrocytes, cells of the meninges. About 80% of primary brain tumors are astrocytomas. The peak incidence occurs in the age interval between 35 and 65 years. The most common histological types of astrocinomas are glioblastoma multiforme and embryonal glioma.

Oncologists identify the following reasons for the increased risk of atypical tumors: * neuroendocrine neoplasms; * exposure to radiation therapy; * diseases of the thyroid gland, ACTH, growth hormone; * gene mutations; * hereditary forms of metabolic disorders; * smoking and alcohol abuse. As a rule, surgery to remove the tumor is performed in cases
