A bone swelling that may be cancerous (see bone cancer) or noncancerous. The most common type of noncancerous bone tumour is an osteochondroma. Other types are osteoma and chondroma (see chondromatosis). Treatment is only necessary if the tumour becomes very large or causes symptoms by pressing on other structures. In such cases, the tumour can be removed by surgery. Osteoclastoma (also called a giant cell tumour), which usually occurs in the arm or leg of a young adult, is tender and painful and has to be removed.
