The risk factors for osteosarcoma are:

  • Age: Teenagers and growing children with growth spurts are at increased risk for osteosarcoma.
  • Gender: Males are at increased risk for osteosarcoma compared to females.
  • Height: Kids with more height are at greater risk than kids with shorter height.
  • Radiation exposure: Exposure to high-dose radiation for treating other cancers increases the risk of osteosarcoma.
  • Underlying medical conditions: Several underlying medical conditions increase the risk of osteosarcoma. These are Paget’s disease of the bone, Rothmund-Thomson syndrome, Li-Fraumeni syndrome, Werner syndrome, Bloom syndrome, Diamond-Blackfan anemia, or hereditary retinoblastoma.
  • Bone infarction: Bone infarction occurs when the vessels supplying the blood to the bones get blocked or damaged, resulting in the death of bone cells. Bone infarction increases the risk of osteosarcoma.
