A brain tumor is an abnormal growth that involves the brain itself or its surrounding structures. This distinction helps us to divide nervous system tumors into two general classes:
Intra-axial tumors: These are tumors which grow within the substance of the brain itself
Extra-axial tumors: These are tumors that originate outside of the actual tissues of the brain, but can involve the brain because of their close proximity to it.
In addition, pineal region tumors, originating from the area of the pineal gland, while technically part of the brain are often considered separately. Tumors vary in location as well as other characteristics such as their typical presenting symptoms, their speed of growth and aggressiveness (whether they are benign or malignant) and their typical locations.
Follow the links below to obtain more information about each type of tumor:
Intra-Axial Tumors:
Gliomas: One of the most common types of primary brain tumors arising from the brain tissue itself, gliomas arise from the supporting cells of the brain, the glial cells.
Astrocytoma: The most common form of glioma, arising from astrocytes.
Ependymoma: From the cells lining the ventricles in the brain.
Glioblastoma Multiforme (AKA grade IV glioma, malignant glioma): The most aggressive form of glioma.
Tumors In Children: There are a few specific types of tumors which affect children.
