In the following there is a list of the more common brain cancer tumor types, 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 investigation of biopsy samples.
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. The percentages relate to how often a particular brain or spinal cord tumor cancer type was found among all of the brain or spinal cord cancers.
Glioblastoma multiforme : 30%
Astrocytoma : 20%
Other gliomas (oligodendroma, ependymoma) : 5%
Meningioma : 20%
Schwannoma (acoustic neuromas) : 10%
Pituitary : 5%
Other tumors : 10%
Spinal cord tumors
Schwannoma : 25%
Meningioma : 35%
Ependymoma : 15%
Astrocytoma : 10%
Other Tumors : 15%
Some of these are benign tumors such as acoustic neuroma (image shown here), which is a schwannomaand is a benign tumor (not cancerous). 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 surrounding healthy brain tissue. For this reason even a benign brain tumor can become an emergency that requires surgery.
