The most common brain tumor types in children (0–14) are: pilocytic astrocytoma, malignant glioma, medulloblastoma, neuronal and mixed neuronal-glial tumors, and ependymoma. [106] In children under 2, about 70% of brain tumors are medulloblastomas, ependymomas, and low-grade gliomas.
Metastatic brain cancer is over six times more common than primary brain cancer, as it occurs in about 10–30% of all people with cancer.

Many recent studies suggest that their location, biological potential and clinical behavior are observed be more variable than previously thought.
Grading of the tumor sample is a method of classification that helps the doctor to determine the severity of the astrocytoma and to decide on the best treatment options. The neuropathologist grades the tumor by looking for atypical cells, the growth of new blood vessels, and for indicators of cell division called mitotic figures. [citation needed]
