What is the surgical process like for removing neuroblastoma?

Depends. A lot depends on the location. Neuroblastoma can occur in the neck, thorax, and/or abdomen. Surgery is necessary to remove or biopsy the mass depending upon its size and involvement of other structures. Once confirmed, then chemotherapy may be required even if completely removed. Prognosis depends upon age of patient and histology.
Depends. Neuroblastomas can be very adherent to other structures. This means they can be "stuck" to things, such as the liver, kidneys, and even large blood vessels (aorta and ivc). The extent to which they involve these structures can help determine how difficult the surgery will be. Good luck.
