Recovery of body image after mastectomy is essential for physical and mental quality of life. Partial or total mastectomy deformities can be reversed by reconstructive surgical procedures. Young women with breast cancer have specific characteristics related to the age of onset of the disease, prognosis and reconstructive expectations. Patient individualization is the key to a successful breast reconstruction. Autologous and prosthetic reconstruction are the two main techniques used for breast reconstruction. Each reconstructive technique has its own indications, advantages and limitations. Timing of the surgery is primarily determined by the requirement for adjuvant radiotherapy, so an immediate or a delayed approach can be recommended. In patients in whom the need for adjuvant radiotherapy is in doubt, a delayed-immediate approach is the best to optimize aesthetic and oncologic outcomes. Prophylactic mastectomy is also being indicated in a growing number of patients. In these patients it is important to choose a similar reconstructive procedure on both sides to achieve breast symmetry.
