what is a glioma

A glioma is a type of tumor that originates from glial cells in the brain or spinal cord. Glial cells are the supporting cells of the central nervous system. There are several types of gliomas, including astrocytomas, ependymomas, and oligodendrogliomas. Gliomas can be cancerous and are classified based on the microscopic appearance of the tumor and the molecular characteristics. They can cause various symptoms, such as nausea, cognitive impairment, seizures, and weakness. Treatment for gliomas often involves a combination of neurosurgical interventions, radiotherapy, and chemotherapy. The prognosis and treatment options depend on the specific type and grade of the glioma
