Osteosarcoma is a type of cancer that starts in the bones. The cancer cells in these tumours look like early forms of bone cells that normally help make new bone tissue. Most osteosarcomas occur in children and young adults. Though Osteosarcoma can develop at any age, teens are mostly affected.
Based on how the cells look under the microscope, osteosarcomas can be classified as high grade, intermediate grade, or low grade. The grade of the tumour tells the doctor about its metastatic characteristics.
