What primary brain tumors?

Tumors that start in brain tissue are called primary brain tumors. (Information about secondary brain tumors appears in the following). Tumors brain is the primary name type of cells or parts of the brain, where they started.

Common primary brain tumors is Gliomas. They begin in the glial cells. There are several Gliomas:

Astrocytoma - a tumor arises from star-form glial cells called astrocytes. In adults, astrocytomas often occur in the brain. In children, occurring in the brain stem, cerebellum and brain. Astrocytoma grade III is sometimes called Astrocytoma is plastic. Astrocytoma grade IV is usually called glioblastoma multiforme.

Gliomas of the brainstem - a tumor occurs in the lower part of the brain. Gliomas brain stem often found in children and youth aged adults.

Ependymoma tumors - from cells line the ventricles or the spinal canal between the Cord. They are common among children and youth.

Oligodendroglioma - This rare tumor cells that are derived from oil that covers and protects nerve. Tumors are usually occur in the brain. They grow very slowly and generally does not extend to surrounding brain tissue. They are common among aged adults.
Some types of brain tumors does not begin in glial cells. Common which are:

Medulloblastoma - This tumor usually occurs in the cerebellum. It is common malignant brain tumors in children. This is sometimes called primitive neuroectodermal tumor.

Meningiomas - This tumor occurs in the meninges. Usually continue to slow.

Schwannoma - a tumor derived from Schwann cells. This line of nerve cells control the balance and hearing. This is the nerve inside the ear. The tumor is also called akustisk neuroma. This often occurs in adults.

Craniopharyngioma - growing tumor from the pituitary gland near the brain. This type of tumor is common in children.

Germ cell tumor of the brain - a tumor derived from stem cells. Germ cell Tumors occur in many brain occur in people younger than 30 years. Common type germ cell tumors of the brain germinoma.

Pineal region tumors - a rare brain tumor that occurs in or near pineal gland. Pineal gland located between the brain and cerebellum.
