What is retinoblastoma?
Retinoblastoma is a type of cancer that forms in the retina (the light-sensitive tissue at the back of the eye). The disease usually occurs in children younger than 5 years and may be in one eye or in both eyes. In some cases the disease is inherited from a parent.
Retinoblastoma is a serious, life-threatening disease. However, with early diagnosis and timely treatment, in most cases, a child's eyesight and life can be saved.
