A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [2]

A nervous system neoplasm is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [ 1 ] [ 2 ] . Nervous system neoplasms include various types of brain and spinal cord tumors, such as gliomas , and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either ...
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
For the concepts of benign and malignant neoplasia see Tumor and Cancer. For primary and secondary neoplasias see Metastasis. A brain tumor composed of benign cells, but located in a vital area (as the brain is), can be considered to be life-threatening — although the tumor and its cells would not be classified as malignant.

Infectious diseases play a role in the development of malignancy, with agents of infectious disease being able to produce a multitude of malignant cells. [10] These include bacterial causes, fungal and parasitic causes and, viral causes. [ 10 ]
Meningiomas arise from arachnoidal cap cells, [17] most of which are near the vicinity of the venous sinuses, and this is the site of greatest prevalence for meningioma formation. Some subtypes may arise from the pial cap cells that migrate during the development together with blood vessels into the brain parenchyma. [18]
Cells have the ability to 'self-destruct'; a process known as apoptosis. This is required for organisms to grow and develop properly, for maintaining tissues of the body, and is also initiated when a cell is damaged or infected. Cancer cells, however, lose this ability; even though cells may become grossly abnormal, they do not undergo apoptosis.
