Types of Brain Tumor

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:

  1. Intra-axial tumors: These are tumors which grow within the substance of the brain itself
  2. 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.
