hi Janvi,
ReplyDeleteA brain tumor is an abnormal growth of cells within the brain, which can be cancerous or non-cancerous. It is intracranial tumor created by abnormal and uncontrolled cell division, normally either in the brain itself.
Primary (true) brain tumors are commonly located in the posterior cranial fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of the brain.
