What is the cause of osteosarcoma?
Osteosarcoma is not due to any previous behavioral, dietary, environmental or genetic factor in most instances. It is a random event. There is no predisposing cause or preventative measure that a patient, parent or other family member could have taken that would have had any bearing on the chances of developing an osteosarcoma. No patient or parent should believe that they somehow contributed to the risk of developing the tumor. In a few very rare cases, there is a genetic link to the disease.
