Retinoblastoma

Printer-friendly version

Retinoblastoma is a type of eye cancer that starts in the retina. The retina is the layer at the back of the eye that detects and senses light.

Retinoblastoma can occur in one or both eyes, and mostly affects infants and young children under three years of age.

Children who have cancers in both eyes or multiple tumours in one eye at the time of diagnosis have an underlying genetic cause for the cancer.
