Malignant tumor is a special disease different from common childhood diseases, which requires special requirements for diagnosis and treatment, and it is impossible to make correct judgment and formulate reasonable treatment plan without relevant training and practical experience. Although most of the late stage children seen in the clinic are not detected by parents in time, there are also quite a few of them are caused by misdiagnosis and mistreatment by non-specialist doctors. Typically, children with neuroblastoma have only anemia and low fever in the early stages, which are often misdiagnosed as iron deficiency anemia or rheumatism. With the continuous development of medicine, the subspecialties are gradually refined, and pediatric tumors have strong professional characteristics, and the diagnosis and treatment are comprehensive, which can not be done by a certain doctor alone.
