According to data from the World Health Organization, breast cancer is the most common malignant tumor of women worldwide, both in developed and developing countries. Often the treatment plan includes a mastectomy - a surgical procedure to remove breast tissue. Breast reconstruction is a very important part of the healing process for breast cancer patients. Reconstruction aims to create a new breast that will match the natural one in appearance and function, thereby contributing to a better psychological state, body perception, sexuality, and self-esteem. Since the goal of breast reconstruction is to create a natural-looking and symmetrical outcome, the surgeon must consider the size of the reconstructed breast. Patients today have more reconstruction options including alloplastic techniques such as tissue expanders/implants or autologous reconstruction and the many variations found within each of these 2 main approaches. The selection of the most appropriate method is based on the patient's overall health condition, physical examination and clinical factors. The reconstruction process can begin at the time of mastectomy (primary reconstruction) or at any time after the procedure (secondary reconstruction). Primary reconstruction should be considered the standard, while delayed reconstruction may be more appropriate for patients with advanced disease. Patients who decide to undergo a reconstruction procedure generally show a high level of satisfaction, experience less stress, have a better assessment of their body image, and more self-confidence compared to women who do not undergo this procedure. The role of the nurse as a team member in the treatment of breast cancer is significant in preoperative preparation and postoperative care. The nurse actively participates in the process of prevention, diagnosis, treatment, and education in the entire process of care.
