Answer:
A very small number of bone cancers (especially osteosarcomas) appear to be hereditary and are caused by defects (mutations) in certain genes. Retinoblastoma is a rare eye cancer in children that can be hereditary. The inherited form of retinoblastoma is caused by a mutation (abnormal copy) of the RB1 gene. Those with this mutation also have an increased risk of developing bone or soft tissue sarcomas. Also, if radiation therapy is used to treat the retinoblastoma, the risk of osteosarcoma in the bones around the eye is even higher. Finally, there are families with several members who have developed osteosarcoma without inherited changes in any of the known genes. The gene defects that may cause cancers in these families haven’t been discovered yet.
They will most likely survive becuase stage one of bone cancer is the most treatable stage.
