Astrocytes, oligodendrocytes, ependymal cells,
and microglial cells are glial cells. Their job is to
support nerve cells.
Gliomas are cancers of glial cells.
Cancer consists of cells that grow faster than
normal cells, invade into normal tissue, and
spread to other areas.
Some gliomas grow and spread faster than
others. There are four cancer grades. Low-
grade gliomas don’t grow or spread as fast as
There are multiple types of gliomas. Types of
gliomas are named after the cell from which
they derived and other cell features (molecular
Larger gliomas are more likely to cause
