Answer 1

The risk factors for primary bone tumors include a history of Paget's disease and prior chemotherapy or radiation therapy.

Step-by-step explanation:

The risk factors for primary bone tumors include both a history of Paget's disease and prior chemotherapy or radiation therapy. Paget's disease is a bone disorder that affects the normal breakdown and formation of bone tissue. It increases the risk of developing bone tumors. Prior chemotherapy or radiation therapy can also increase the risk of developing primary bone tumors.
