Brain Tumor Types
Types of Brain Tumors
There are more than 120 different types of brain and CNS tumors. The tumors included in our directory reflect the statistically most common primary brain and CNS tumors according to data collected by the Central Brain Tumor Registry of the United States (CBTRUS).Neurofibroma
Neurofibromas are tumors of the nerve fibers. The term neurofibromatosis refers to two different genetic diseases characterized by skin abnormalities and nervous system tumors: Neurofibromatosis type 1: Also called NF-1 or
Meningioma
Meningiomas are often benign tumors arising from the coverings of the brain and spinal cord. They represent about one-third of all primary brain tumors and occur most frequently in middle-aged
Medulloblastoma
Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The various
Lymphoma
Lymphoma is a cancer that arises from the cells of the lymphatic system. In the brain, this type of cancer is called Primary CNS Lymphoma (PCNSL).
Lipoma
Lipomas are rare, benign (noncancerous) tumors composed of fatty tissue. They are sometimes associated with other congenital abnormalities of the nervous system. Lipomas vary in size. Single or multiple tumors may
Hemangioma
A hemangioma is an abnormal buildup of blood vessels in the skin or internal organs. Two types of hemangiomas are discussed here: Hemangioblastoma: These tumors are benign, slow-growing, and well defined.
Glioma
“Glioma” is a general term used to describe any tumor that arises from the supportive (“gluey”) tissue of the brain. This tissue, called “glia,” helps to keep the neurons in
Glioblastoma (GBM)
Glioblastomas (also called GBM) are malignant Grade IV tumors, where a large portion of tumor cells are reproducing and dividing at any given time. They are nourished by an ample and abnormal tumor vessel blood supply. The tumor is predominantly made
