Radiotherapy has played an important role in the treatment of breast cancer. It is frequently given following conservative surgery for ductal carcinoma in situ (DCIS) or stage I and II invasive breast cancer. Its role as adjuvant therapy following mastectomy in selected patients with stage I and II disease is currently being defined, and it is an essential component of the combined modality approach for stage III disease. Radiation represents an important therapeutic option for the palliation of metastases to sites such as bone and brain and may be used alone or in combination with surgery to control recurrent disease in the chest wall or regional nodes following mastectomy. This chapter discusses the role of radiation in the treatment of DCIS, stage I and II breast cancer, locally advanced breast cancer, local-regional recurrence, and metastatic disease (Table 1).
