Biopsy
A biopsy is perhaps the most definitive test to diagnose Ewing sarcoma and bone cancer. During the procedure, your doctor will take a small sample of the affected bones and send it to the lab for further testing. The test can find out precisely what kind of cancer that you are experiencing and the current stages. There are two ways to carry out a biopsy. An open procedure can be done under a general anesthetic. The doctor will make an incision and remove a tissue sample. A core needle biopsy can be done with a general or local anesthetic. In some cases, you might need both options to ensure the most comprehensive diagnosis. [2]
