A brain tumor is associated with the unrestricted growth of brain cells; resulting into formation of a lump. Brain tumors can be cancerous as well as non-cancerous and can hamper the normal functioning of the brain.

Moreover, abnormal growth of brain cells can build-up pressure inside the skull too, causing severe brain damage. Brain tumors are commonly categorized into primary as well as secondary, depending upon its original location.

Risk factors of brain tumor include past medical or family history, exposure to radiations, smoking, and to certain carcinogenic chemicals.
