Abstract
Breast cancer is the most common female cancer in the US and the second most common cause of cancer death in women.Approximately 268,670 new cases of invasive breast cancer and an estimated death toll of 41,400 women in 2018 (Siegel et al., 2018).Management of invasive breast cancer should be based on the clinical extent and pathologic characteristics of the tumor, in addition to the age of the patient, menopausal status, some biologic prognostic factors, and the preference and psychological profile of the individual patient, optimally in a multidisciplinary setting.(Halperin et al.,2013)Surgical,medical,and radiation oncology remain the primary therapeutic disciplines in the management of breast cancer.
