How can you prevent osteosarcoma?

You usually can't: Osteosarcoma is a very rare cancer. Of 300 million people in the us, there are about 800 cases a year. Usually it occurs randomly, but rare cases are due to genetic disorders, preexisting benign conditions (paget's etc.) or radiation. Other than avoiding radiation, there is not much you can do. That being said, the chances of getting osteosarcoma in the first place are very low.
