Some astrocytomas grow very slowly and others can be aggressive cancers that grow quickly. Astrocytoma is a type of cancer that can form in the brain or spinal cord.
Why do Neuroglial cells become cancerous?
Like cancers in other parts of the body, gliomas are thought to originate from stem cells. In this case, gliomas arise from neural precursor cells that otherwise create neurons and glia. These stem cells may become cancerous when harmful mutations occur in genes that normally suppress tumor formation.

What are glioependymal (neuroglial) cysts?
Intracranial glioependymal (neuroglial) cysts: a systematic review The data collected from this review shows that GECs are rare and very often are erroneously named. They are congenital benign lesions with a neuroectodermal origin that share many radiological characteristics with a variety of intracranial benign cysts.
What causes a brain cyst to grow without any symptoms?
Some cysts are “silent” (cause no symptoms) until they grow large. In some cases, you may have a problem related to the area of the brain the cyst is growing in. In other cases, the symptoms may be due to blockage of the normal flow of CSF. This can cause increased pressure on the brain (intracranial pressure).
What is the difference between a brain abscess and neoplastic cyst?
A brain abscess happens anywhere in the brain as a single t or multiple cysts. Abscesses are usually caused by a bacterial infection . They are sometimes caused by a parasite or a fungus. A neoplastic cyst is due to a benign or malignant tumor. When a brain tumor starts outside the brain, it is called metastatic.
