They perform many essential roles and make up the supportive tissue of the brain. When there is a defect in an astrocyte that causes it to grow out of control, the brain tumor that forms is called an astrocytoma.</p> <p>Astrocytomas come in four major subtypes: pilocytic astrocytoma (grade 1), fibrillary astrocytoma (grade 2), anaplastic astrocytoma (grade 3), and glioblastoma multiforme (grade 4).</p> <p>Low-grade astrocytomas (grades 1 and 2), seen more often in kids and young adults, are highly curable because they usually grow slowly, don't spread, and usually are fairly easy to remove unless found in areas where surgery would be difficult. After surgery, there's a chance that chemotherapy or radiation won't be needed.</p> <p>High-grade astrocytomas (grades 3 and 4), which tend to be seen more in adults, are more aggressive and invade deeper into the tissues. This makes them more difficult to treat. Treatment usually includes surgery, chemotherapy, and radiation.</p> <h3>Keep in Mind</h3> <p>Treatment for brain tumors is getting better all the time, but a lot depends on the location of the tumor. Astrocytomas that can be completely removed surgically are much more likely to be cured, while those that can't be completely removed are, in general, less curable.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
Brain TumorsBrain tumors are the second most common group of childhood cancers. Treatment requires a very specialized plan involving a team of medical specialists.https://kidshealth.org/ws/RadyChildrens/en/parents/brn-tumors.html/ff2bd11c-a3d8-4bb3-bb58-edd97dd13a31
Brain and Nervous SystemThe brain controls everything we do, and is often likened to the central computer within a vast, complicated communication network, working at lightning speed.https://kidshealth.org/ws/RadyChildrens/en/parents/brain-nervous-system.html/1e2a5004-5865-4069-97fd-5488c31075b9
Brain and Nervous System CancersThese cancers are the most common type of cancer in children. When discovered early, they often can be cured.https://kidshealth.org/ws/RadyChildrens/en/parents/brain-tumors.html/527c1203-9898-45b5-8dba-3de70f76df5d
ChemotherapyChemotherapy (chemo) is treatment with medicines that stop the growth of cancer cells.https://kidshealth.org/ws/RadyChildrens/en/parents/chemotherapy.html/54f93018-4955-4463-b067-5621e285210f
