Team Tough Titties Knockin Out Cancer's blog: "Types and Grades of Brain Tumors"

Astrocytoma / Glioma
Astrocytomas are tumors that arise from brain cells called astrocytes. Gliomas originate from glial cells, most often astrocytes.
Atypical Teratoid / Rhabdoid Tumor (ATRT)
This rare, high-grade tumor occurs most commonly in children younger than 2.
Brain Stem Glioma
The brain stem consists of the midbrain, pons and medulla located deep in the posterior part of the brain.
Choroid Plexus Tumor
The choroid plexus papilloma is a rare, benign tumor most common in children under the age of 2.
Craniopharyngioma
Craniopharyngiomas result from the growth of cells that have failed to migrate to their usual area just below the back of the skull early in fetal development.
Ependymoma
Ependymomas arise from cells lining the passageways in the brain that produce and store the cerebrospinal fluid or CSF.
Ganglioglioma
These rare, benign tumors arise from ganglia-type cells, which are groups of nerve cells.
Germ Cell Tumors (Brain)
The brain stem consists of the midbrain, pons and medulla located deep in the posterior part of the brain.
Gliomatosis Cerebri
This condition is similar to glioblastoma multiforme (GBM), but the cells of gliomatosis cerebri are more scattered and widespread.
Infant Brain Tumors
Medulloblastoma and ependymal tumors account for about 50 percent of tumors.
Medulloblastoma / PNET
Medulloblastomas are tumors that arise in the posterior fossa region of the brain. The exact cell of origin is not known.
Oligodendroglioma
These tumors arise from oligodendrocytes, a type of supportive brain tissue...
