What is retinoblastoma?

ANSWER

Retinoblastoma is a rare form of eye cancer that usually happens in childhood. It starts in the retina -- the part of the eye that senses light and sends pictures to the brain.

Fewer than 300 children in the U.S. are diagnosed with it each year. Usually, it's found before they turn 2.
