Neuroblastoma is a type of cancer that originates in immature nerve cells, called neuroblasts. It usually occurs in children and can develop in various parts of the body such as the adrenal glands, neck, chest or abdomen. The disease often starts in one area and may spread to other parts of the body through the bloodstream or lymphatic system. Neuroblastoma is a rare cancer, accounting for about 6-10% of all childhood cancers. It usually occurs before the age of five but can also occur in older children and adults. Treatment options include surgery, chemotherapy, radiation therapy or a combination of these methods. The prognosis depends on various factors such as the stage of the cancer, the patient's age, and whether the cancer has spread to other parts of the body.
