A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord.They are cancerous but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
Medulloblastoma is a common type of primary brain cancer in children. It originates in the part of the brain that is towards the back and the bottom, on the floor of the skull, in the cerebellum, or posterior fossa. [3] The brain is divided into two main parts, the larger cerebrum on top and the smaller cerebellum below towards the
