Most people with primary bone cancer will need a combination of different treatments. The treatments that are used are surgery , chemotherapy and radiotherapy .
Surgery is a very important part of treatment and is used to remove the tumour in the bone.
If surgery is not possible then radiotherapy, which is particularly effective in Ewing's sarcoma , may be used instead. Chemotherapy is an important treatment for most people with osteosarcoma and Ewing's sarcoma. It is often given before surgery and may shrink large tumours enough to avoid amputation. The course of chemotherapy will then continue after surgery. When radiotherapy is used to treat Ewing's sarcoma, it is most often given after or instead of surgery.
