Osteosarcoma is the most common type of bone cancer that appears mostly in teens and young adults during growth spurts. It affects males twice as often as females and those who are taller than average. The cancer spreads quickly because the cells reproduce non-stop unlike normal cells. Symptoms include pain, swelling, bruising, and hair loss in the affected limb. Treatments involve chemotherapy, radiation, and surgery to stop the cancer spreading and remove the affected area.
