Neuroblastoma is not a contagious disease, and currently, the cause of neuroblastoma is not very clear. In some cases, it is related to genetic factors, and in other cases, it might be related to the effects of radiation and drug-induced genetic mutations. There is no definitive consensus on this yet.

For relatives caring for someone with neuroblastoma, there is no need to worry about contagion. This is simply a form of tumor within the skull. It will continue to grow, spread, and disseminate within the body on its own, but it cannot be transmitted to another individual. Therefore, there's no need for undue concern. Prompt treatment to extend the patient's lifespan and reduce suffering is crucial to better serve the patient.
