Complete Information on Brain tumor

Brain is a tender, soft people of tissue. It is protected by the bones of the skull and three slim membranes called meninges. Cancer begins in cells, the construction blocks that take upward tissues. Tissues take upward the organs of the system. Normally, cells rise and split to organize original cells as the system needs them. When cells rise older, they perish, and original cells go their spot. Sometimes this peaceful procedure goes incorrect.

There are two types of mind tumors. Primary brain tumors that originate in the brain and metastatic (secondary) brain tumors that originate from cancer cells that have migrated from other parts of the body. Most primary brain tumors originate from glia (gliomas) such as astrocytes (astrocytomas), oligodendrocytes (oligodendrogliomas), or ependymal cells (ependymoma). There are also mixed forms, with both an astrocytic and an oligodendroglial cell component. These are called mixed gliomas or oligoastrocytomas. Secondary or metastatic brain tumors originate from malignant tumors (cancers) located primarily in other organs.

Their incidence is high than that of main mind tumors. The symptoms of mind tumors bet on their size and position in the mind. Symptoms frequently are caused by harm to essential tissue and force on the mind as the tumor grows within the modest place in the skull. They may be caused by swelling and a buildup of graceful around the tumor, a circumstance called edema. Symptoms too may be payable to hydrocephalus, which occurs when the tumor blocks the flowing of cerebrospinal fluid and causes a build-up in the ventricles.

Other symptoms of loss of feeling in the arms or legs , sickness, stumbling or lack of coordination in walking , abnormal eye movements or changes in vision, drowsiness changes in speech and changes in personality or memory.

Treatment usually consists of surgery (traditional or computer-assisted), radiation, chemotherapy — or a combination of those treatments. Corticosteroids such as dexamethasone to reduce brain swelling.
