[edit] Brain Cancer (Tumor Types)

Types of brain tumors:

In the following there is a list of the more common brain cancers and what types occur both in the central nervous system as well as in the spinal cord. It shows that the more common brain tumors are glioblastoma and astrocytoma, all of which are based on histology slides. Click on the links for further details.

The following tables of frequency of occurrence are based on data from Ref.1 and 2 where neurosurgeons operated on patients with various brain tumors and sent the surgical samples for histological analysis to the pathologist.

Brain tumors
Name of tumor:	Percentage:
Glioblastoma multiforme	30%
Astrocytoma	20%
Other gliomas (oligodendroma, ependymoma)	5%
Meningioma	20%
Schwannoma|(acoustic neuromas)	10%
Pituitary	5%
Other tumors	10%

Spinal cord tumors
Name of tumor:	Percentage:
Schwannoma	25%
Meningioma	35%
Ependymoma	15%
Astrocytoma	10%
Other tumors	15%

Some of these are benign tumors such as acoustic neuroma, which is a schwannoma, which has abnormal cells, but no cancer cells. However, as there is only so much space within the human skull, these tumors become a danger to the person who has it. The increased intracranial pressure threatens the survival of the brain tissue. For this reason even a benign brain tumor can become an emergency that requires surgery.
