What is Brain Tumor (Glioma)?

A glioma is a type of brain tumor that originates from glial cells, which support nerve cells. It is the most common primary brain tumor in adults, with severity ranging from low-grade (slow-growing) to high-grade (aggressive, such as glioblastoma). Key facts include that gliomas account for about 30% of all brain tumors and require specialized, multidisciplinary care for optimal outcomes.
