Living with Oligoastrocytoma

A brain tumor made of two types of supportive brain cells that grow too fast.

Understanding Oligoastrocytoma

Oligoastrocytoma is a brain tumor made of two kinds of glial (supportive) brain cells that multiply quickly to form a mass.

The two cell types are oligodendrocytes and astrocytes. These glial cells normally protect and support nerve cells. Because the tumor has two cell types, it is called a mixed glioma.
