Rare cancers in children make up fewer than 1 in 30 of all childhood cancers and can broadly be grouped as:
- rare cancers that only affect children, such as pancreatoblastoma, malignant rhabdoid tumours and melanotic neuroectodermal tumours of infancy
- cancers that usually only affect adults, such as cancers of the digestive system, the thyroid and the adrenal gland
- rare cancers in the head and neck area, such as nasopharyngeal cancer
- rare hormonal/endocrine cancers, such as phaeochromocytoma
- rare brain tumours, such as meningioma
- rare skin cancers, such as melanomas.
