What are the symptoms of osteosarcoma?
Most people who have osteosarcoma do not feel or look sick. An osteosarcoma tumor may cause a dull aching pain in the bone or joint around the tumor. Often, there is a firm swelling or lump in the area of the pain. This swelling is caused by the tumor growing inside the bone.
If the cancer is in a leg bone, the person 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.
