What does a neuroblastoma tumor feel like?
Tumors in the abdomen (belly) or pelvis: One of the most common signs of a neuroblastoma is a large lump or swelling in the child’s abdomen. The child might not want to eat (which can lead to weight loss). If the child is old enough, they may complain of feeling full or having belly pain.
What does a neuroblastoma lump look like?
Neuroblastoma that spreads to the skin can give it a blue black colour, as if it were bruised. Sometimes, there are small, raised, discoloured lumps. These can look like blueberries on the skin.
Are neuroblastomas malignant?
Neuroblastoma is the most common malignant (cancerous) extracranial solid tumor of childhood. It develops from the tissues that form the sympathetic nervous system, which is the part of the nervous system that regulates involuntary body functions.
How long can you live with neuroblastoma?
Low-risk group: Children in the low-risk group have a 5-year survival rate that is higher than 95%. Intermediate-risk group: Children in the intermediate-risk group have a 5-year survival rate of around 90% to 95%. High-risk group: Children in the high-risk group have a 5-year survival rate of around 50%.
What are the symptoms of neuroblastoma in adults?
Other signs and symptoms that may indicate neuroblastoma include:
- Lumps of tissue under the skin.
- Eyeballs that seem to protrude from the sockets (proptosis)
- Dark circles, similar to bruises, around the eyes.
- Back pain.
- Fever.
- Unexplained weight loss.
- Bone pain.
Does neuroblastoma show in blood tests?
Neuroblastoma cells also often make these catecholamines, so these same metabolites can be detected in blood and urine. If the neuroblastoma cells are making catecholamines, the amount of HVA and VMA in urine or blood will be higher than expected.
Can a blood test detect neuroblastoma?
Neuroblastoma often spreads to the bone marrow (the soft inner parts of certain bones). If blood or urine levels of catecholamines are increased, then finding cancer cells in a bone marrow sample is enough to diagnose neuroblastoma (without getting a biopsy of the main tumor).
How fast do neuroblastomas grow?
Some neuroblastomas grow slowly (and some might even shrink or go away on their own), while others can grow quickly and spread to other parts of the body. Neuroblastoma happens most often in babies and young children. It is rare in children who are more than 10 years old.
Are neuroblastomas benign?
Neuroblastoma is the most immature, undifferentiated, and malignant tumor of the three. Neuroblastoma, however, may have a relatively benign course, even when metastatic. Thus, these neuroblastic tumors vary widely in their biologic behavior.
Can adults survive neuroblastoma?
Neuroblastoma in adults is extremely rare. It affects 1 in 10 million adults per year. Adults with neuroblastoma have a significantly worse outcome than children with neuroblastoma, with a 5-year survival rate average of 36.3% . However, early diagnosis can help treatment be more effective.
Where does neuroblastoma start?
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. Most neuroblastomas begin in the abdomen, either in an adrenal gland or in sympathetic nerve ganglia.
How can you detect neuroblastoma?
Tests and procedures used to diagnose neuroblastoma include:
- Physical exam. Your child’s doctor conducts a physical exam to check out any signs and symptoms.
- Urine and blood tests.
- Imaging tests.
- Removing a sample of tissue for testing.
- Removing a sample of bone marrow for testing.
How do you rule out neuroblastoma?
Why are neuroblastomas more common in children?
Children with a family history of neuroblastoma are more likely to develop this type of cancer. But about 98% to 99% of the time, neuroblastoma is not inherited (or, passed down in families). Children born with other congenital anomalies (birth defects) may have a higher risk of developing neuroblastoma.
Where are neuroblastomas found?
Neuroblastoma most commonly arises in and around the adrenal glands, which have similar origins to nerve cells and sit atop the kidneys. However, neuroblastoma can also develop in other areas of the abdomen and in the chest, neck and near the spine, where groups of nerve cells exist.
