question: 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.
