Genetic Testing for Retinoblastoma

Retinoblastoma is a cancer that starts in the retina, the very back of the eye. It can also spread to other parts of the body, including the brain and bones. The disease primarily affects young children. It can be either hereditary or non-hereditary. Children with hereditary retinoblastoma often develop retinal tumors in both eyes within the first years of life. . Genetic counseling and testing clarify the risk for retinoblastoma in children with a family history of the disease and improve outcomes at reduced cost, justifying making testing available to all patients with a personal or family history of retinoblastoma.
