Neuroblastoma 4.7 cm is more serious and its treatment is more difficult, but early diagnosis and treatment can improve the prognosis. Neuroblastoma is highly malignant and is the most common solid extracranial tumor in childhood. Most children have localized extension or even distant metastasis at the time of diagnosis, so the treatment outcome is often unsatisfactory. Since neuroblastoma originates from the sympathetic nerves, it can easily invade and encapsulate the accompanying midline blood vessels, making surgical treatment difficult and risky. If neuroblastoma within one year of age can be detected early and treated with comprehensive treatment such as surgical resection, radiotherapy and chemotherapy in time, the prognosis can be greatly improved and mortality rate can be reduced. If neuroblastoma is found in the first year of life, you should go to the hospital in time and have standardized treatment under the doctor’s guidance, so as to avoid delaying the condition and causing serious consequences.
