What is a Pilocytic Astrocytoma?

  • A pilocytic astrocytoma is a brain tumor that originates from star-shaped cells called astrocytes. Astrocytes are a kind of glial cell, cells that support and nourish neurons in the brain. An astrocytoma is a type of glioma, and pilocytic astrocytomas are low-grade gliomas — a family of slow-growing tumors that arise from glial cells. They are the most benign and most treatable of the gliomas, with a cure rate of over 90 percent.
