In other cases, the cells sometimes mature on their own into normal ganglion cells and stop dividing which makes the tumor a benign ganglioneuroma - see below.
Not all childhood autonomic nervous system tumors are malignant cancerous. Some tumors are benign non-cancerous , and some can have both benign and cancer cells within the same tumor. If a child is thought to have one of these tumors, it is usually removed by surgery and looked at carefully with a microscope to see if it has areas of cancer cells which would make it a ganglioneuroblastoma. If the final diagnosis is ganglioneuroma, no other treatment is needed. The sympathetic nervous system The brain, spinal cord, and the nerves that reach out from them to all areas of the body are all part of the nervous system.
It includes: Nerve fibers that run along either side the spinal cord. Clusters of nerve cells called ganglia plural of ganglion at certain points along the path of the nerve fibers. Nerve-like cells found in the medulla center of the adrenal glands. The adrenals are small glands that sit on top of each kidney. These glands make hormones such as adrenaline [epinephrine] that help control heart rate, blood pressure, blood sugar, and how the body reacts to stress.
Neuroblastomas Neuroblastomas are cancers that start in early nerve cells called neuroblasts of the sympathetic nervous system, so they can be found anywhere along this system. It's common to feel overwhelmed. This is a guide through the symptoms, diagnosis and treatment of neuroblastoma. We have information about where you can get support to help you cope.
Neuroblastoma is a rare cancer that affects children, mostly under the age of 5 years. It develops in early nerve cells called neuroblasts and often starts in the tummy. The most common symptom of neuroblastoma is a lump in the tummy abdomen. Find out about the other possible symptoms of neuroblastoma. Your child will need a number of tests if their doctor suspects they have neuroblastoma. Find out what tests they might have. Find out how doctors group neuroblastoma, the staging systems they use and what risk groups there are.
Read about how doctors make decisions about treating neuroblastoma and get up to date information on what each treatment might involve. There are a number of treatment options for neuroblastoma that has not gone away with treatment, or has come back. Your child's neuroblastoma treatment options will depend on several factors.
Neuroblastoma in the abdomen — the most common form — may cause signs and symptoms such as:. Contact your child's doctor if your child has any signs or symptoms that worry you.

In general, cancer begins with a genetic mutation that allows normal, healthy cells to continue growing without responding to the signals to stop, which normal cells do.
Cancer cells grow and multiply out of control. The accumulating abnormal cells form a mass tumor. Neuroblastoma begins in neuroblasts — immature nerve cells that a fetus makes as part of its development process. As the fetus matures, neuroblasts eventually turn into nerve cells and fibers and the cells that make up the adrenal glands. Most neuroblasts mature by birth, though a small number of immature neuroblasts can be found in newborns. In most cases, these neuroblasts mature or disappear.
