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.
Retinoblastoma is a rare cancer originating in the part of the eye called the retina. The retina is a thin layer of nerve tissue that coats the back of the eye and enables the eye to see. Most cases (about 60 percent) involve only one eye (unilateral), but in some children, both eyes may be involved (bilateral). About 300 children are diagnosed with retinoblastoma in the United States each year.
