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 malignant (cancerous) tumor of the retina, the thin nerve tissue that lines the back of the eye which senses light and forms images. It may be compared to the film in a camera that perceives images and sends these to the brain for interpretation.ost retinoblastoma occurring in only one eye is not hereditary; when the disease occurs in both eyes it is always hereditary. However, while less common, retinoblastoma may occur in only one eye and may still be hereditary and passed on to children, or inherited in siblings.
