My daughter has neuroblastoma. What is it in a nutshell?

Nervous system tumor. Neuroblastoma is a tumor that starts in nervous system cells, usually from the sympathetic nervous system. The most common site is in the abdomen often starting in the adrenal gland. It is a cancer of children. Its prognosis is variable with some resolving spontaneously and others very aggressive. It is treated with surgery and/or chemotherapy. Younger children do better.
