Neuroblastoma is a cancer of types of cell nerve tissue called neuroblasts. Neuroblasts are young nerve cells mostly found in:
- the adrenal glands (near the kidneys)
- the tissues around the spinal cord in the neck, chest, abdomen and pelvis.
Many neuroblastomas start in the adrenal glands.
Neuroblastoma is most common in infants and children under five years of age. It is rare in children over 10 years old and very rare in adults.
