Is neuroblastoma benign or malignant?
Benign tumors are less likely to spread. Malignant tumors are aggressive, grow quickly, and often spread. A ganglioneuroma is less malignant in nature. A neuroblastoma (occurring in children over 1 year old) is usually malignant.
Is neuroblastoma a type of leukemia?

What is the meaning of neuroblastoma?
Definition of neuroblastoma : a malignant tumor formed of embryonic ganglion cells.
Is Neuroblastoma curable?
Neuroblastoma grows and reacts differently to treatment in different people. This is called the disease’s clinical behavior. Some children are cured with surgery alone or surgery with chemotherapy (see Types of Treatment). Others have a very aggressive disease that is resistant to treatment and difficult to cure.
Can a child recover from stage 4 Neuroblastoma?
Children with stage 4S neuroblastoma containing cells that seem to have normal chromosomes are also in this group. The children in this group have a five-year survival rate between 90% and 95%.
Does neuroblastoma come back?
Relapsed neuroblastoma refers to the return of neuroblastoma in patients who have already undergone treatment for the disease. Approximately half of children who are treated for high-risk neuroblastoma and achieve an initial remission will have the disease come back.
Can neuroblastoma come back?
How old does a child have to be to get neuroblastoma?
Neuroblastoma most commonly affects children age 5 or younger, though it may rarely occur in older children. Some forms of neuroblastoma go away on their own, while others may require multiple treatments.
Where does neuroblastoma start in the fetus?
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.
What is the 5 year survival rate for neuroblastoma?
Based on categories of risk, these are the five-year survival rates for neuroblastoma: For low-risk patients: about 95 percent For moderate-risk patients: between 80 and 90 percent For high-risk patients: about 50 percent
How is neuroblastoma treated in high risk patients?
Internal radiation uses needles, seeds, wires or catheters (tubes) to deliver the radiation directly into or close to the cancer. High-risk patients are given more intense treatments. Patients with neuroblastoma are considered high-risk when the tumor cannot be surgically removed and has spread:
