Breast cancer is the most common cancer among Polish women [1], thus, the problem of surgical treatment of breasts, especially with regard to conserving and/or reconstruction surgery, is extensively discussed. Currently, in Poland, efforts are made to increase the number of oncologic and reconstructive breast centers which offer specialized treatment of this cancer, the so-called ‘Breast Units’ [1]. This paper analyzes methods of reconstructions, discusses the techniques used in particular types of surgeries and additionally informs the reader of the oncological aspects of the procedures. Based on literature, statistical data of breast reconstructions from Poland and the world are presented. Moreover, complications and psychological aspects of mammary gland surgery are dealt with, and the aesthetic effects of breast reconstructions are discussed. To support of our findings, we also present selected clinical cases from the oncological and reconstructive point of view.
