- Retinoblastoma is a rare type of eye cancer that can affect young children. It mostly affects children under 3 years of age.
- It can be in 1 or both eyes and affects the back of the eye (the retina). The retina sends signals to the brain to help you see.
- Treatments are available and it can usually be treated successfully if it's found early.
- Retinoblastoma is often linked to a change in a gene that controls the growth of the eye. It can run in families.
