What is class II astrocytoma?

A astrocytoma of grade II, sometimes known as a low -degree astrocytoma, is a type of cancer or malignant neoplasm that develops from cells called astrocytes inside the brain or spinal cord. Astrocytes are shaped as stars and as part of a group known as glial cells is their function to support nerve cells. A tumor that grows from gli cells is called glioma and astrocytomas are the most common type of glioma. Astrocytoms can be sorted on a scale I to IV and can be classified as a high quality or low class. Grade II astrocytoma, which is of low quality, will tend to grow more slowly and is less likely to spread to other parts of the body compared to high quality tumor. Most often astrocytomas grow from the main part of the brain or brain. Symptoms may develop, or sometimes the tumor blocks the circulation of the fluid that surrounds the brain, leading to a sudden increase in pressure inside the skull. As a result of increased intracranial pressure, vomiting may beEsti head and visual disorders.

Diagnostics of grade II usually require MRI or magnetic resonance. Sometimes CT or computed tomography can be used instead. The patient's eyes may be examined to seek signs of swelling in the brain. In some cases, surgery can be performed to remove cells from the tumor so that they can be examined under a microscope. If the pressure inside the skull is higher than usual, it will be necessary to reduce it before any further procedures.

Class II's treatment of class II usually involves surgery to remove the tumor as fully as pos.ible. Sometimes it may be difficult to cut all tumor depending on its size and accurate position and other treatment, such as radiotherapy, can be used to destroy the remaining tumor tissue. Instead of surgery can occasionally be used radiotherapy if the tumor Nedo isSurgens, or if there is a risk that surgery will damage part of the brain. The view of the II astrocytoma is better if most of the tumor can be removed, but partial removal can help improve symptoms.
