Cancer is a disease caused by the uncontrolled proliferation of cells in a certain part of the body and the spread of these cells. Cancer, the incidence of which is increasing, affects the patient and his family physically, psychologically, socially and spiritually, and the symptoms experienced reduce the quality of life. Breast cancer is the most common cancer in women. Tumorous tissue is removed by mastectomy, one of the breast cancer treatment methods, but individuals are exposed to physiological, psychological and social problems. It has been revealed in the literature that the education given before surgery prepares patients for surgery, reduces anxiety, accelerates the treatment process, and reduces the use of analgesia. Özberksoy et al. (2009) stated that preoperative education given to breast cancer patients reduced their postoperative pain and anxiety levels.Yutmaz (2018) stated that the video-assisted training given before mastectomy reduced pain levels on the tenth postoperative day and increased comfort. Marize et al. (2018) found that as a result of the education applied to patients who were planned for breast cancer surgery, their anxiety levels decreased and their knowledge about treatment increased. Bozdemir (2021) states that the training given to women with breast cancer after surgery is effective in preventing lymphedema and increasing the quality of life. In our study, it is aimed to examine the effect of structured education to be given to patients who are planned for mastectomy on the quality of early postoperative recovery.
