[Indications, technique, results and value of breast saving surgery in breast cancer]

Breast preservation is by no means a standard treatment modality for breast cancer. An increasing number of unsatisfactory results have been observed despite the fulfillment of requirements necessary for adequate treatment. Excellent surgical technique is a solid basis for good cosmetic result. According to the interim analysis of the German breast preservation study a tumor biopsy with a small margin of healthy tissue together with a lower axillary dissection can be considered a sufficient surgical procedure. The relationship between tumor size and size of the breast is one of the most important factors determining contraindications for breast preservation. Adequate instruction of the patient still remains a major problem for most doctors. If the patient is properly informed about the operation quality of life is not substantially altered after mastectomy and breast reconstruction compared with breast preservation therapy.
