Approximately 30 years ago, when I was in oncology at the Children's Hospital 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.
大约在30年以前， 当我还在 费城儿童医院的肿瘤科 一对父子走进我的办公室 他们两人都没有了右眼， 当我询问了病史，很明显 父亲和儿子都患有一种罕见形式的 遗传性的眼睛肿瘤，视网膜母细胞瘤， 父亲知道他把那种噩运 传给了儿子。
