**8. Conclusions**

The diagnostic evaluation of bone tumors, therefore, must be carried out systematically, starting with the history and physical examination, which will guide the diagnostic hypotheses and necessary complementary tests. A patient referred for specialized evaluation should not be delayed to obtain staging images for investigation, being standard radiography is sufficient for this purpose. A biopsy is the last procedure to be performed. It depends on the initial staging to be planned and should be performed at the service where the patient will start his treatment and preferably by the doctor responsible for the surgical treatment.
