Objective: Breast cancer is one of the most common types of cancer in women, and the first-line treatment for it is surgery. Depending on the patient’s condition, either of the following may be selected: breast-conserving surgery, modified radical mastectomy, radical mastectomy, or simple mastectomy. According to treatment guidelines, chest wall involvement, axillary lymph involvement, and tumors >5 cm should be treated with radiotherapy. Postoperative radiotherapy is required to provide local control and prevent distant metastases. In addition, chemotherapy in early stage breast cancer with axillary involvement increases survival by preventing distant metastases. The contribution of radiotherapy to local and remote control after mastectomy was examined. Methods and Results: In this retrospective study, 1,073 breast cancer patients who were admitted to our clinic during a period of five years were included and their postoperative radiotherapy treatment results were evaluated. Conclusion: In patients undergoing radiotherapy, a 6% local recurrence and 88% survival was found in five years. Also, locoregional recurrence was statistically and significantly lower in those undergoing radiotherapy (p=0.0001).
