5Medulloblastoma
Medulloblastoma is a type of brain tumor that occurs in the cerebellum. It is graded 4 and also the fast-growing form in this list. This tumor usually spreads via your cerebrospinal fluid pathways, but there are many ways to treat it. These include chemotherapy, radiation therapy, and surgery. Children are often at a higher risk of experiencing this type than adults. In fact, medulloblastomas belong to a class called embryonal tumors, which would also happen in different parts of your central nervous system. [5]
