Breast cancer is a disease requiring multidisciplinary management including surgery, medical and radiation oncology, radiology, pathology, nuclear medicine, genetic counseling, and psychological support. Each member of the team needs to be updated continuously on breast cancer treatment because of its rapidly changing nature. From the diagnostic procedures to operations and even in metastatic stages of breast cancer, surgeons play an essential part in multidisciplinary teams. After standard surgical options, oncoplastic breast surgery is rapidly becoming one of the most important surgical topics that should be learned by attending surgeons. The idea of writing this book stemmed from a collaboration between the European Academy of Senology (EAoS), European Institute of Oncology (IEO), Euro-Asian Society of Mastology (ESOMA), and SENATURK (Turkish Academy of Senology), which have been working together to promote better training in breast care for professionals. The book offers invaluable support for breast surgeons by covering critical and essential information in senology. It will also greatly benefit the other members of multidisciplinary teams, surgery residents, gynecologists, and plastic and reconstructive surgeons.
