What are some signs of osteosarcoma?
Your child or teenager may have a dull aching pain in the bone or joint around the site of the osteosarcoma. The pain can awaken him or her from sleep. Often, there is a firm swelling or lump in the area of the pain. This swelling is caused by a tumor growing inside the bone.
If the cancer is in a leg bone, your child or teenager may limp. Also, the muscles in the arm or leg that has the osteosarcoma may look smaller than the muscles in the opposite arm or leg. Sometimes, the bone can break in the area of the tumor, because the tumor weakens the bone.
