Genetic testing of children with retinoblastoma reduced the number of disease risk screenings required for their relatives, according to a study involving patients at Texas Children's Cancer Center in Houston. "By systematically including genetic testing in the care of retinoblastoma patients, we could eliminate the need for such screening in the majority of relatives and save both health care costs and potential risks of the anesthesia," said senior study author Dr. Sharon E. Plon.
