Approximately 30 years ago, when I was in oncology at the Children's Hospital in Philadelphia, a father and a son walked into my office and they both had their right eye missing, and as I took the history, it became apparent that the father and the son had a rare form of inherited eye tumor, retinoblastoma, and the father knew that he had passed that fate on to his son.
Pirms aptuveni 30 gadiem, kad es strādāju Filadelfijas Bērnu slimnīcas onkoloģijas nodaļā, manā kabinetā ienāca tēvs un dēls, un viņiem abiem nebija labās acs. Izpētot slimības vēsturi, kļuva skaidrs, ka gan tēvam, gan dēlam bija iedzimta reta acs audzēja forma — retinoblastoma, un tēvs zināja, ka viņš bija nodevis to tālāk savam dēlam.
