Neuroblastoma
Neuroblastoma is the second most solid tumour in children which affects around 7% of all children with cancer. It is a cancer that progresses from immature nerve cells found in several areas of the body. Neuroblastoma most frequently occurs in and around the adrenal glands, which have similar origins to nerve cells and sit over the kidneys. It can also occur in other areas of the abdomen chest, neck and near the spine, where clusters of nerve cells exist. Neuroblastoma begins in very initial forms of nerve cells, frequently found in an embryo or fetus. Occasionally it forms before birth and can be found during a fetal ultrasound.
