Symptoms and diagnosis

Neuroblastoma signs and symptoms

Neuroblastoma is the most common tumor in infants and young children occurring outside the central nervous system. It is usually diagnosed before the age of 5 and most commonly develops in the abdomen or along the spine.

Neuroblastoma symptoms vary depending on the location of the tumors in the body. Symptoms might include:

  • Unusual lump or mass

  • Swollen stomach or belly pain

  • Problems breathing or swallowing

  • Weight loss or lack of appetite

  • Swelling in the face or throat

  • Chronic fatigue and general aches and pains

  • Problems with urination or bowel movements

Diagnosing neuroblastoma

Your child’s doctor will do a full physical exam and take a detailed medical history. Additional tests could include:

  • Urine test, to determine a substance called catecholamines that is produced by the tumor

  • Blood tests

  • Magnetic resonance imaging (MRI)

  • Computerized tomography (CT) scan

  • X-rays

  • Bone scan

  • Biopsy of the tumor

  • Radiation therapy: High energy X-rays are used to shrink tumors and prevent them from growing

  • Chemotherapy

  • Immunotherapy

  • Bone marrow transplant
