GLIOMAS. Gliomas are usually secondary to abnormal growth of glia cells, and often contain necrotic tissue and small areas of hemorrhage. They are highly malignant. Gliomas are part of a family of tumors that include Astrocytomas which are among the most frequently occuring type of tumors, and the Glioblastoma Multiforme which is an exceedingly malignant and deadly tumor.

GLIOMA. Brain tumors are usually graded on a 4 point scale. Gliomas are considered Grade 3 lesions and have their peak rate of incidence between the ages of 40 and 60 and occur more frequently among males than females. They have the potential to infiltrate wide areas of the cerebrum. Astrocytomas are Grade 1 lesions, "low grade" gliomas are classified as Grade 2 lesions, and the deadly and exceedingly malignant Glioblastoma Multiforme is a Grade 4 tumor.

Carcinoma. Intracranial carcinomas are tumors that metastasize from other parts of the body, usually the lungs or breasts. They are of three types: those which grow along the meninges at the brainstem spinal junction, those which grow along the inner skull and dura, and those which infiltrate and scatter throughout the gray matter and subcortical white matter.
