Osteosarcoma is a type of bone cancer that typically develops in the cells that form new bone tissue. It is the most common primary malignant tumor of the bone and usually occurs in children and young adults, although it can occur at any age.
The exact cause of osteosarcoma is unknown, but certain risk factors have been identified. These include age (it is more common in adolescents and young adults), previous radiation therapy, and certain genetic conditions.
