<s>[INST] Hi, my son has been diagnsed with Gaglineuromablastoma- Doctor said it has benign cells, Pathology and Histology are favourable and my son has no symtons - there is a mass of 7 by 10 cm in sympathatic nerves - doctor said he is not too worried - doesnt recommend surgery and says he will monitor it in 3 months with another MRI. I am worried as I read evrywhere that surgery is the best treatment for this. Please advise. [/INST] Hi, I had gone through your question and understand your concerns. Yes, surgery is the only option for cure, so I am sure that there was some misunderstanding with doctors. Sometimes chemo and radiotherapy may be chose nut surgery is first option and should be done initially. The quicker a ganglioneuroblastoma is diagnosed, the quicker it can be treated and prevented from spreading. Treatment usually begins with surgical removal of the tumor. Chemotherapy and radiation are then used to prevent regrowth. If a tumor contains only benign cells, surgery is most likely the only treatment needed. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. </s>
