 ==Common Risk Factors==
-:* '''Retinoblastoma occurs in heritable and nonheritable forms'''.
-:: A child is thought to have the heritable form of retinoblastoma when one of the following is true:
-:::* There is a family history of retinoblastoma.
-:::* There is a certain mutation (change) in the RB1 gene. The mutation in the RB1 gene may be passed from the parent to the child or it may occur at the time of conception.
-:::* There is more than one tumor in the eye or there is a tumor in both eyes.
-:::* There is a tumor in one eye and the child is younger than 1 year.
-:: After diagnosis and treatment in a child with heritable retinoblastoma, new tumors may continue to form for a few years. Regular eye exams to check for new tumors are usually done every 2 to 4 months for at least 28 months.
-::* Nonheritable retinoblastoma is retinoblastoma that is not the heritable form. Most cases of retinoblastoma are the nonheritable form.
