Occasionally therapeutic doses of radiation may be used to treat benign processes, such as heterotopic bone formation, meningiomas, and other benign proliferative diseases. Radiation has a very prominent role in the management of breast cancer after lumpectomy, as adjuvant therapy after mastectomy, in the management of locoregional relapse of disease, and in the palliation of metastatic disease. Management of breast cancers can typically cover up to 20% to 25% of a general radiation oncology practice. The next few chapters will cover in more detail the role of radiation therapy after breast conserving therapy, the rapidly evolving role of partial breast irradiation, postmastectomy radiation, and the role of radiation in palliation and metastatic disease.
