- astrocytoma - The tumor arises from glial cells called astrocytes. In adults, astrocytomas most frequently occur in the cerebrum. In children, they occur in the brain stem, the cerebrum and cerebellum. A Class III astrocytoma is sometimes a so-called anaplastic astrocytoma. A class IV astrocytoma is usually referred to as glioblastoma multiforme.
- brain stem glioma - The tumor occurs in the lowest part of the brain. Brainstem gliomas are the most commonly diagnosed in young children and middle-aged adults.
- Ependymoma - The tumor cells, it is clear from this line of the chambers or the central canal of the spinal cord. They are most often in children and young adults.
- Oligodendroglioma - This arises from rare tumor cells, which fatty substance that covers and protects the nerves. These tumors usually in the cerebrum. They grow slowly and not spread into surrounding brain tissue. They are most often in middle-aged adults.
Some types of brain tumors do not begin in glial cells. The most common are:
- medulloblastoma - This cancer usually arises in the cerebellum. It is the most common brain tumors in children. It is sometimes also a primitive neuroectodermal tumor.
- Meningioma - This tumor is in the meninges. It grows slowly.
- Schwannoma - that a tumor arises from a Schwann cells. These cells line the nerve that controls balance and hearing. This is nerve in the inner ear. The tumor is also an acoustic neuroma. It occurs most frequently in adults.
- Craniopharyngioma - The growing tumor at the base of the brain near the pituitary gland. This type of tumor occurs most often in children.
- germ cell tumor of the brain - the tumor arises from a germ cell. Most germ cell tumors in the brain that occur in people younger than 30th The most common type of germ cell tumor of the brain is a Germinoma.
- pineal region tumor - This is rare brain tumor in or near the pineal gland. The pineal gland is located between the cerebrum and cerebellum.
