The following are the most prevalent kinds of brain cancer in adults:

  • Astrocytomas. These normally begin in the cerebrum, the portion of the brain that takes up the greatest area. They can cause seizures or behavioral changes.
  • Meningiomas. Adults are most likely to develop these types of primary brain tumors. They are especially common among people in their 70s and 80s. They begin in the meninges, the brain's lining. They can be in grades one, two, or three. They are non-cancerous, and metastasis is uncommon.
  • Oligodendrogliomas. These develop in the cells that form the protective layer around nerves. They're usually in grades one, two, or three. They typically grow slowly and do not spread to surrounding tissue.


The most prevalent tumor types in children are:

  • Medulloblastoma is a type of tumor that develops in the cerebellum. A primitive neuroectodermal tumor is another name for it. It is a fourth-grade level.
  • Grade I or II astrocytoma: This low-grade tumor can form anywhere in the brain in youngsters. Juvenile pilocytic astrocytoma is the most frequent type of astrocytoma in children. It's the first grade.
  • Ependymoma is a tumor that develops from cells lining the ventricles or central canal of the spinal cord. Children and young adults are the most typically affected. It could be in the first, second, or third grade.
  • Glioma of the brainstem is a tumor that develops in the lowest portion of the brain. A tumor might be low-grade or high-grade. Diffuse intrinsic pontine glioma is the most prevalent kind.
