Neuroblastoma is a type of cancer that is caused by immature nerve cells that are found in different areas of the body. This condition commonly arises in and around the adrenal glands. However, it may also occur in other areas of the abdomen as well as in the chest, neck, and near the spine, where groups of nerve cells exist.

Commonly neuroblastoma affects children who are five years of age or younger, but it sometimes occurs in older children as well.

Certain forms of neuroblastoma disappear on their own, but others may require multiple treatments. Treatments generally depend on several factors.


The signs and symptoms of neuroblastoma can vary depending on the part of the body being affected.

Neuroblastoma in the abdomen: The most common form of neuroblastoma is neuroblastoma in the abdomen, which can cause signs and symptoms such as-

  • Abdominal Pain
  • A mass under the skin which isn’t tender when touched
  • Changes in bowel habits, such as diarrhea or constipation


Neuroblastoma in the chest: This causes signs and symptoms such as –

  • Chest pain
  • Wheezing
  • Changes to the eyes; this can include drooping eyelids and unequal pupil size


Other signs and symptoms that might indicate neuroblastoma include the following-

  • Lumps of tissue under the skin
  • Eyeballs that seem to protrude from the sockets
  • Fever
  • Unexplained weight loss
  • Dark circles, similar to bruises, around the eyes
  • Back pain
  • Bone pain


If your child is showing any signs and symptoms that you find worrisome, then you need to consider seeing your doctor.

Causes & risk factors

Cancer generally begins with a genetic mutation that allows normal and healthy cells to continue growing without responding to the signals to stop, which normal cells do. Cancer cells continue to grow, eventually multiplying out of control. The accumulating abnormal cells eventually end up forming a mass or a tumor.

Neuroblastoma begins in neuroblasts, which are immature nerve cells that form on a fetus as part of its development process. As the fetus matures, neuroblasts turn into nerve cells and fibers as well as the cells making up the adrenal glands. Most neuroblasts mature by birth, but sometimes a small number of immature neuroblasts are found in newborns. In most cases, these neuroblasts mature or eventually disappear within some time. Others, however, form a tumor, which is termed neuroblastoma.

The initial genetic mutation that leads to neuroblastoma is still unknown.

Several lifestyle factors like body weight, physical activity, diet, and tobacco use are known to play a major role in several types of cancers. These factors, however, take many years to influence cancer risk, and therefore, they are not considered to play much of a role in childhood cancers, like neuroblastomas.

There are also no environmental factors are known to increase the chance of getting neuroblastoma.

Children who have the familial form of neuroblastoma, usually come from families having one or more members who have had neuroblastoma as infants.

Children having familial neuroblastoma can sometimes develop two or more of these cancers in different organs. For example, they can develop it in both adrenal glands or in more than one sympathetic ganglion.

According to certain studies, children with birth defects might have an increased risk of developing neuroblastoma. It is possible that some of the links between birth defects and neuroblastoma might be related to changes in genes that happen during fetal development.


For the diagnosis of neuroblastoma, your doctor might use the following tests and procedures-

Physical Exam

Your child’s doctor will most likely conduct a physical exam for checking any signs or symptoms. You will also be asked questions about your child’s habits and behaviors.

Urine and Blood Tests

These can help to indicate the cause of any signs or symptoms that your child is experiencing.

Imaging Tests

Imaging tests such as CT scan, X-RAY, MRI, or MIBG scan can help to reveal a mass which can indicate a tumor.


Biopsy Image

If a mass is found, your child’s doctor is likely going to remove a sample of the tissue for laboratory testing. This is known as a biopsy.

Removing a sample of bone marrow for testing

Your child might also need to undergo bone marrow biopsy and bone marrow aspiration procedures, as this can help to see if the cancer has spread to the bone marrow.

Once the neuroblastoma has been diagnosed, your doctor might need to do further testing to determine the extent of the cancer and to see how far it has spread.

The stages are indicated from O to IV. The lower the stage is, the less severe the cancer is. By stage IV, the cancer is considered to be advanced and have spread to other areas of the body.


Your child’s doctor is going to select the treatment plan based on several factors. Factors can include the age of your child, the stage of your cancer, the type of cells involved in the cancer, and whether there are any abnormalities in the chromosomes and genes.

Treatment options can include any of the following:


Brain Surgery Image

Surgery involves surgeons removing cancer cells surgically, with the help of scalpels and other tools. In children with low-risk neuroblastoma, surgery to remove the tumor is usually the only treatment needed.

Whether your doctor can remove the tumor completely, depends on the location and size of the tumor. Tumors that are attached to nearby vital organs, like the lungs or the spinal cord, might be too risky to remove.

If the neuroblastoma is intermediate or severe, surgeons generally try to remove as much of the tumor surgically, after which other treatments such as chemotherapy and radiation might be used to kill the other remaining cancer cells.

This treatment involves using chemicals to destroy cancer cells. Unfortunately, this treatment also damages healthy cells, which can include the cells in the hair follicles and in the gastrointestinal system, which can cause side effects.

Radiation therapy

Radiation therapy uses high-energy beams, such as X-rays, in order to destroy cancer cells. Children with low-risk or intermediate-risk neuroblastoma might go for this treatment. It is generally considered if surgery and chemotherapy are unsuccessful. Children having severe neuroblastoma might also need radiation therapy after chemotherapy and surgery to prevent the cancer from occurring again.

However, it is important to note that though radiation therapy affects the area where it is aimed, some healthy cells may be damaged by the radiation as well.


Immunotherapy is a treatment method that uses drugs that work by signaling your body’s immune system to fight cancer cells.

Bone marrow transplant

Children suffering from severe neuroblastoma might need to receive a transplant using stem cells collected from bone marrow

Before the bone marrow transplant, which is also known as stem cell transplant, the child will need to undergo a procedure that filters and collects stem cells from his/her blood. The stem cells are stored for later use. Then high doses of chemotherapy are administered to kill any remaining cancer cells in the body. The child’s stem cells are then injected into your body, where they are now able to form new, healthy blood cells.


Neuroblastoma can lead to the following complications:

Spread of cancer – Neuroblastoma can spread or metastasize to different parts of the body, such as the lymph nodes, liver, bone marrow, skin, and bones.

Spinal Cord Compression – Tumors can grow and press on the spinal cord, which can cause spinal cord compression, which may further lead to pain or even paralysis.


Although there is no known and proven way to prevent neuroblastoma, certain cancers can be reduced with certain lifestyle changes such as maintain a healthy weight and quitting smoking.
