Medulloblastoma is the second-most frequent brain tumor in children after pilocytic astrocytoma [37] and the most common malignant brain tumor in children, comprising 14.5% of newly diagnosed brain tumors. [38] In adults, medulloblastoma is rare, comprising fewer than 2% of CNS malignancies. [39]
Secondary, or metastatic, brain tumors are about four times as common as primary brain tumors, [2] [10] with about half of metastases coming from lung cancer. [2] Primary brain tumors occur in around 250,000 people a year globally, and make up less than 2% of cancers. [3] In children younger than 15, brain tumors are second only to acute ...
