There are many different types of brain tumours, which form when abnormal brain cells grow rapidly in different areas of the brain and the spinal cord. Not all brain tumours are cancerous, and how they are classified will depend on the location, type of cell and how aggressive it is.
Common types of brain tumours in children and young adults include:
- Gliomas, including astrocytomas
- Primitive neuroectodermal tumors (PNETs), now known as embryonal tumours
- CraniopharyngiomaDiffuse intrinsic pontine glioma (DIPG)
Brain tumours are the most common form of solid tumours in children across the world. Out of all childhood cancers, leukaemia is the most common childhood cancer (~30%) followed by brain tumours (~30%).
