Possible signs of neuroblastoma include bone pain and a lump in the abdomen, neck, or chest. The most common symptoms of neuroblastoma are caused by the tumor pressing on nearby tissues as it grows or by cancer spreading to the bone. These and other symptoms may be caused by neuroblastoma. Other conditions may cause the same symptoms.
