A brain tumor takes place when abnormal growth of cells occurs within the brain, and it can be non-cancerous or cancerous. It is known as an intracranial tumor which is created by the uncontrolled and abnormal cell division normally in the brain all by itself.
Primarily, the tumors in the brain are located in posterior cranial fossa in children and in the anterior two by third of the cerebral hemispheres in the adults, although they can affect any part of the brain.
In US year 2005, as estimated there were 43,800 cases of brain tumor; reported by the central brain tumor registry of US, statistical reports 2005-2006, which accounted for around 1.4percent of all cancers reported, 2.4percent of deaths which were caused by cancer, 20 to 25percent because of pediatric cancer, eventually making it nearly 13,000 deaths each year in the United States only because of brain tumor.
The symptoms and reasons of brain tumor may depend upon two most crucial factors: the tumor volume (size) and the location where tumor has taken place. These are the two factors beginning in the stage of infection correlating with the nature of the brain tumor in some cases. It happens that the tumor grows slowly and show the symptoms late or grows quickly showing early symptoms; one of the frequent reasons to seek medical attention to the brain tumor cases.
Depending upon the tumor size and location along the damage it may cause to the areas surrounding the brain’s structure either because of infiltration or compression or any other kind of neurologic systems may occur which can be tremors, behavioral and cognitive impairment, double vision, changes in the personality, hemi paresis, facial paralysis, hypo esthesia, visual field impairment, ataxia, aphasia etc.
The above mentioned symptoms are not specifically for the brain tumor, but these may be caused because of high neurologic conditions such as traumatic brain injury or stroke. What matters is the location of the functional system and the trauma which it affects.
There are different types of brain tumor, which are; brain metastases, glob blastema multiforme, mixed glioma’s, mixed glioma’s, medulla blastema, expend moa, astrocytoma, craniopharyngioma, CNS lymphoma, brain stem glioma, Shawna noma, germinoma, oligodendroglioma and men angioma
