title: [Radiotherapy in the conservative management of breast cancer].
abstract: Breast conserving therapy is now considered standard treatment in patients with early breast cancer, and it yields equal local control and survival equal to those of radical mastectomy, in Europe and the United States. After many reports from western countries, Japanese surgeons started conservative treatment for early breast cancer. The aim of radiotherapy is to eradicate residual tumor after quadrantectomy or lumpectomy. Indication for this management by Fujio Kasumi at the Cancer Institute Hospital is T1, N0, M0. We reported here the method of radiotherapy, that is energy of photon, treatment field and total dose, which are discussed by the study group of the Japanese Society for Therapeutic Radiology and Oncology.
