Neuroblastoma

Neuroblastoma often begins in the nerve tissue of the adrenal glands. There are two adrenal glands, one on top of each kidney in the back of the upper abdomen. The adrenal glands produce important hormones that help control heart rate, blood pressure, blood sugar, and the way the body reacts to stress. Neuroblastoma may also begin in the chest, in nerve tissue near the spine in the neck, or in the spinal cord.
