How can neuroblastoma cause heterochromia?

ANSWER

Neuroblastoma is a cancer of the nerve cells that usually affects children under 10. When tumors press on nerves in the chest or neck, sometimes kids have a drooping eyelid and a small pupil. They can also get heterochromia. See a doctor right away if your child's eye color changes.
