Neuroblastoma
Neuroblastoma, a tumour of the sympathetic nerve tissue, is the most common
solid tumour in children after brain tumour. It usually arises from the suprarenal
gland deep in the abdomen. But it can also occur in the chest, the neck and
the pelvic cavity. Fifty percent of the cases are found in children under the
age of 2 years. This tumour grows rapidly and may already have spread beyond
the site of origin when the child is first examined.
