Neuroblastoma is the most common solid tumour found in children.
Neuroblastoma develops in immature nerve cells called neuroblasts, which are specialised cells in the nervous systems. The cells grow out of control and form a tumour, typically in the adrenal glands above the kidneys or anywhere along the spinal cord. It can also develop in the chest, abdomen or pelvis.
Symptoms of neuroblastoma includes a lump or swelling in the abdomen, chest or neck, pain, fatigue, loss of appetite and/or weight, bulging or drooping eyes, bone pain and fever.
Surgery, chemotherapy, radiation and immunotherapy or stem cell transplants are common treatments for neuroblastoma.
Neuroblastoma commonly affects children under 5 years old, with most cases diagnosed[JS1] before age 2.
