General Information About Childhood Brain Stem Glioma
Some childhood brain stem gliomas are diagnosed and removed in surgery.
If the tumor has not spread widely within the brain stem or has not been diagnosed by MRI, a biopsy may be done by removing part of the skull and using a needle to remove a sample of the brain tissue. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are found, the doctor will remove as much tumor as safely possible during the same surgery.
Certain factors affect prognosis (chance of recovery) and treatment options.
The prognosis (chance of recovery) and treatment options depend on:
- The type of brain stem glioma.
- Where the tumor is found in the brain and if it has spread within the brain stem.
- Whether or not the child has a condition called neurofibromatosis type 1.
- Whether the tumor has just been diagnosed or has recurred (come back).
