Behind the Tumor: Glioma

Glioma is a collective term referring to a group of tumors originating in the glial cells of the brain, which provide support to the primary brain cell type, neurons.These tumors commonly occur in the cerebral hemispheres, the brain’s largest outer section responsible for vital functions such as movement, speech, cognition, and emotions. Gliomas can also initiate in the brain stem, regulating essential functions like breathing, blood pressure, and heartbeat. Additionally, they may develop in the optic nerves and cerebellum—the part of the brain overseeing balance and non-cognitive functions.
