Brain Tumor Types.

There are different brain tumor types.  They are usually named after the type of cell they develop from. They can also be named after the area of the brain they are growing in. Different brain tumor types are as:

 Secondary brain tumor:

It is a 1st type of brain tumor types. A secondary (metastatic) brain tumor occurs when cancer cells spread to the brain from a primary cancer in another part of the body. … Most often, cancers that spread to the brain to cause secondary brain tumors originate in the lung, breast, kidney, or from melanomas in the skin.

Ependymoma:

It is a 2nd type of brain tumor types. Ependymoma  arises from the ependyma, a tissue of the central nervous system. Usually, in pediatric cases the location is intracranial, while in adults it is spinal. The common location of intracranial ependymoma is the fourth ventricle.

Craniopharyngioma:

It is a 3rd type of brain tumor types. Craniopharyngioma is derived from pituitary gland embryonic tissue, that occurs most commonly in children but also in adults in their 50s and 60s. People may present with bitemporal inferior quadrantanopia leading to bitemporal hemianopsia, as the tumor may compress the optic chiasm.

Meningioma:

It is a 4th type of brain tumor types. Meningioma is  also known as meningeal tumor, is typically a slow-growing tumor that forms from the meninges, the membranous layers surrounding the brain and spinal cord. Symptoms depend on the location and occur as a result of the tumor pressing on nearby tissue.

Primitive neuroectodermal tumor:

It is a 5th type of brain tumor types. Primitive neuroectodermal tumor (PNET) is a malignant (cancerous) neural crest tumor. It is a rare tumor, usually occurring in children and young adults under 25 years of age. The overall 5 year survival rate is about 53%.
