Here you will find comprehensive information from the National Cancer Institute about bone cancer, including Ewing's family of tumors, osteosarcomas, bone fibrous histiocytomas, and chondrosarcoma. Information is also available for secondary bone cancer, that has spread to the bone from another part of the body (such as the prostate, breast, or lung). You will find treatment options by type of disease presented in two formats -- for patients and for health professionals. You can search for clinical trials involving patients with bone cancer, and read a fact sheet: "Bone Cancer: Questions and Answers". Information is also available in Spanish.
