Brain tumor

A brain tumor or brain tumour, is an intracranial solid neoplasm, a tumor within the brain.

Brain tumors include all tumors inside the human skull (cranium) or in the central spinal canal. They are created by an abnormal and uncontrolled cell division, usually in the brain itself, but also in lymphatic tissue, in blood vessels, in the cranial nerves, in the brain envelopes (meninges), skull, pituitary gland, or pineal gland.
