Neuroblastoma

Neuroblastoma is a malignant (cancerous) tumor of infants and children that develops from nerve tissue.

Neuroblastoma can occur in many areas of the body. It develops from the tissues that form the sympathetic nervous system (the part of the nervous system that controls body functions, such as heart rate and blood pressure, digestion, and levels of certain hormones).

Neuroblastoma most commonly begins in the abdomen in the tissues of the adrenal gland, but it may also occur in other areas. It can spread to the lymph nodes, liver, bones, and bone marrow.

The cause of the tumor is unknown. Neuroblastoma is most commonly diagnosed in children before age 5. The disorder occurs in approximately 1 out of 100,000 children and is slightly more common in boys.
