Risk+Factors,+Facts,+&+Bibliography


 * ===Bone cancer does not have a clearly defined cause, but researchers speculate that several factors can increase the likelihood of developing bone cancer. ===
 * ===Controllable factors include the exposure to high doses of radiation therapy from a previous cancer, and other common carcinogens. However, a common x-ray is not powerful enough to cause bone cancer ===
 * ===Uncontrollable factors include heredity, especially with those individuals who had defects in their skeletal system. Osteosarcoma, for instance, is common in children affected by the Li-Fraumeni syndrome, Rothmund-Thompson syndrome, and Retinoblastoma (a rare form of eye cancer). ===
 * ===Age and sex are also an uncontrollable factor, as young men between the ages of 4 and 25 are more likely to develop bone cancer than other groups. ===
 * ===Interestingly enough, these risk factors vary with the typo of tumor, and while they may apply to Osteosarcoma, they may not be relevant to the other types. ===
