**3.1 Surgery**

Surgery is the oldest and still the most widely used treatment modality that is available for breast cancer patients and can be accomplished by mastectomy, removal of the entire breast or by breast-conserving surgery often termed lumpectomy of cancer. If the tumor is detected at early stage before spreading, surgery alone might be sufficient to reach complete remission. When the tumor is detected after spreading with distant metastases, surgery is frequently used in combination with radiotherapy or chemotherapy (Keshtgar et al, 2010).
