High-Grade Astrocytomas

Astrocytomas are the most common type of childhood glial cell cancer (glioma). High-grade astrocytomas - also called high-grade gliomas - tend to grow and spread more quickly than low-grade astrocytomas.

About high-grade astrocytomas

High-grade astrocytomas are a type of high-grade glioma (brain tumors that form in glial cells) and include anaplastic astrocytomas and glioblastomas.

Like low-grade gliomas, high-grade gliomas start in star-shaped brain cells called astrocytes, a type of glial cell.

High-grade vs. low-grade brain tumors

The term high-grade is used to describe cancer cells and tissues that look abnormal under a microscope.

High-grade tumors tend to grow and spread more quickly than low-grade tumors.

High-grade cancers usually have a worse chance of recovery than low-grade cancers. They may need treatment right away and treatment that is more aggressive.

Knowing whether a pediatric brain tumor is low-grade or high-grade may help guide your child’s treatment.
