Understanding Malignant Brain Tumor Types

Understanding Malignant Brain Tumor Types

Malignant brain tumors can be categorized based on their cell origin. Here are common types:

1. Gliomas: These tumors originate in glial cells. Subtypes include astrocytomas, oligodendrogliomas, and ependymomas.
2. Medulloblastoma: Arising from neuroectodermal cells, it primarily affects the cerebellum in children and is highly malignant.
3. Meningioma: Developing from meninges (protective brain and spinal cord layers), most are benign, but some require treatment.
4. Schwannoma: Originating from Schwann cells, these tumors occur in the brain or peripheral nerves.
5. Pituitary adenoma: Developing in the pituitary gland, most are benign, but some can be malignant.
6. Primary CNS lymphoma: A rare brain cancer originating in the lymphatic system within the central nervous system.

Accurate diagnosis guides effective treatment.
