Neuroblastoma is a type of cancer that primarily affects young children, usually under the age of 5. It develops from immature nerve cells called neuroblasts, which are found in various parts of the body, most commonly in the adrenal glands located on top of the kidneys. This cancer can spread quickly and may cause symptoms like abdominal pain, swelling, or bruising. The exact cause of neuroblastoma is not well understood, but certain genetic factors may increase the risk. Treatment options often include chemotherapy, radiation therapy, and sometimes surgery to remove the tumor. Early diagnosis and intervention are crucial for improving outcomes in affected children.
