Retinoblastoma is a rare cancer, and there are no widely recommended screening tests to look for retinoblastoma in children without symptoms. Still, many retinoblastomas are found early by parents, relatives, or a childâs doctor.he RB1 gene defect can be found by a special blood test, so most doctors now advise that children with parents or siblings with a history of retinoblastoma have this genetic test done during the first few weeks after birth. The results of the test then help define how often eye exams should be done.
All children with bilateral eye involvement and somewhere between 10 and 15 percent of children with unilateral disease have the hereditary form of retinoblastoma. To determine on a molecular level whether a person has the hereditary or nonhereditary form of retinoblastoma, a genetic test may be performed.
