Neuroblastoma is the most common cancer found in infants.
Neuroblastoma is a rare cancer of the sympathetic nervous system; a nerve network
that carries messages from the brain throughout the body. These solid tumors which
take the form of a lump or mass may begin in nerve tissues in the neck, chest, abdomen,
pelvis, or most commonly in the adrenal gland. They may also spread to other areas
of the body, including bone and bone marrow.
The median age for tumor discovery is two years, and it occurs somewhat more in
boys than girls. Its frequency is second only to brain tumors and it is seldom seen
in children over 14 years old.
