What is Gliom?

Glioma is a tumor resulting from gial cells in the brain or spine. Gli cells or neuroglies are supportive cells of nerve tissue that neurons provide nutrition and other physical support. Gliomas occur most often in the brain. The cause of gliomas is unknown, although genetic predisposition is a factor and exercise during adolescence can reduce the risk of a person of gliomas later in life. Gliomas

can be classified according to their location, cell type or degree. When gliomas are classified according to location, they are characterized whether they appear above or below cerebelli terrolia, the membrane of the brain separating the brain above the brain below. Glioma emerging over the Cerebelli Terolius is called supratentorial glioma, while one under the territory of Cerebelli is an infratentorial glioma. The first is more common in adults and the second in children.

In the classification of cell types, gliomas are named after the typunormal cell are most similar. Ependymomas are gliomas reminiscent of ePendymal cells,Neuroglial cells that line the ventricular system of the brain and spinal cord, a set of structures containing cerebrospinal fluid. Astrocytoms are gliomas resembling astrocytes, star -shaped neuroglia that perform multiple functions. Oligodendrogliomas resemble oligodendrocytes, which are used to isolation of axons of neurons. Gliomas can also be mixed cell types, in which case they are called oligoastrocytomas.

The third possible classification system for gliomas is their mark, which can be either low or high. Low degree gliomas are well differentiated and benign; Gliomas of high quality are undifferentiated or anaplastic and malignant. A low -degree glioma patient has a better prognosis. Low degree gliomas grow slowly and often do not require treatment if there are no symptoms. High quality gliomas, on the other hand, grows very quickly and almost always grows back after surgical excision.

gliomasIn the brain, headaches, seizures, nausea, vomiting and skull nerve disorders can cause, while spinal cord gliomas can cause weakness, pain or numbness on the limbs. Gliom on the optical nerve can cause loss of vision. Gliomas cannot spread through the bloodstream, but can spread to other areas of the nervous system through the cerebrospinal fluid.

There is no glioma cure, and patients with glioma of high -quality degree have very high mortality. Glioma is usually treated with a combination of radiation therapy, chemotherapy and surgery depending on the location and severity of the tumor. Medication, namely angiogenic blockers such as bevacizumab, which block the growth of new blood vessels, are sometimes also part of treatment. More experimental treatment use gene therapy to infect cancer cells by virus.
