No: Glioma is a broad term that refers to cancers in the brain. Many are malignant but some are benign.

No: Gliomas arise from brain astrocytes, ependyma cells(lines the ventricles), or oligodendrocytes (cells that make the coverings of nerves). The most common gliomas are the astrocytomas. These are graded such that grades 1 and 2 are low grade while 3 and 4 are malignant. The grade 4 is the glioblastoma which is the most malignant. Treatment and prognosis is dependent upon the pathological grade.
