Neuroblastoma is found almost exclusively in children and is different in many ways from tumours which occur in adults. It has its own treatments, which can be different from those undergone by other people with cancer.
Neuroblastoma is characterised by the very different ways in which tumours progress (this is sometimes called heterogeneity). Some tumours regress spontaneously, with no requirement for treatment. Some tumours are completely cured with surgery or chemotherapy and some tumours require intensive and extended treatments.
Neuroblastoma is also described as aggressive, meaning it often spreads (metastasises) quickly and extensively throughout the body. By the time they are diagnosed with neuroblastoma, around half of the children affected have already reached a phase in which the disease has spread; increasing their risk factor.
