Overview
Symptoms
The first symptoms of neuroblastoma are often vague and may include fatigue and loss of appetite. Later symptoms depend on tumor locations. In the abdomen, a tumor may cause a swollen belly and constipation. A tumor in the chest may cause breathing problems. Tumors pressing on the spinal cord cause a feeling of weakness. A tumor in the head may cause the eyes to start to swell outwards and turn black due to the pressure from behind. Often because symptoms are so unclear, half of all neuroblastomas have already spread (metastasized) to other parts of the body by the time suspicions are raised and a diagnosis is made.
