Osteosarcoma is otherwise called primary bone cancer. It is more prevalent among children and young people. Osteosarcoma occurs when a single cell of the bone becomes anomalous. As a result, it grows uncontrollably to form a mass of cancerous tissue. This tissue mass also resembles the bone, but they contain immature cells and hence fragile in nature. Osteosarcoma is more likely to develop in long bones, particularly around the knee. The main reason for the onset of such a condition is radiation exposure. Surgery and oral chemotherapy are two such treatment options often suggested for the treatment of osteosarcoma.
