gliomas

Gliomas are a type of tumor that originate from glial cells in the brain or spinal cord, which support and protect nerve cells. They can vary in aggressiveness, from slow-growing to highly malignant. Common types include astrocytomas, oligodendrogliomas, and ependymomas. Symptoms depend on the tumor's size and location but may include headaches, seizures, or neurological changes. Diagnosis involves imaging tests like MRI and biopsy. Treatment options can include surgery, radiation therapy, and chemotherapy. The prognosis varies widely based on the specific glioma type, grade, and individual factors.
