    What is the outlook for Childhood Astrocytomas ?
    ### Response:
    Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) and treatment options depend on the following:         - Whether the tumor is a low-grade or high-grade astrocytoma.    - Where the tumor has formed in the CNS and if it has spread to nearby tissue or to other parts of the body.
