Astrocytomas are the most common type of childhood brain tumour. They are generally subdivided into high-grade or low-grade tumours, with high-grade astrocytomas being the most malignant of all brain tumours.
Anaplastic astrocytoma (also called grade 3 astrocytoma) and glioblastoma multiforme (GBM or grade 4 astrocytoma) are the most common brain tumours in adults. These are malignant brain gliomas. They can sometimes spread to other parts of the brain.
