This tumor is quite cureable. The small cyst version is one that, when surgically removed, is gone for good. Forget about all the fears, just thank God that your child will do well. In some cases the definitive treatment is surgery. In most, however, surgery serves as a temporizing measure that will keep a child out of trouble for long enough to get through definitive therapy that will hopefully eliminate of the tumor.
Brain surgery is usually the easiest part of a child's treatment.
Unfortunately, chemotherapy is the hard part of brain tumor treatment. It is only required for the more aggressive tumors. As a rule, chemotherapy should be even more aggressive than the tumor itself. The trials which are imposed both on the child and parents are legion. Bravery and an unremitting attitude of hope are required by all involved.
