Background The aim of this study was to investigate the effect of preoperative psychological well-being on postoperative pain and physiological parameters in women undergoing mastectomy for breast cancer. Methods This descriptive, cross-sectional study was conducted at the General Surgery Clinic of a Training and Research Hospital in Istanbul between July 2024 and April 2025. A total of 69 women who underwent mastectomy participated in the study. Data were collected using a demographic information form, psychological well-being scale, visual analog scale for pain, and a physiological parameter form including pulse rate, blood pressure, body temperature, and respiratory rate. Results Women who underwent bilateral mastectomy reported significantly lower psychological well-being and higher postoperative pain levels compared to those who underwent unilateral mastectomy (p < .05). Conclusions In conclusion, this study shows that preoperative psychological well-being is related to postoperative pain levels and physiological parameters. Psychological assessment and support should be integrated into preoperative nursing care, particularly for patients undergoing bilateral mastectomy.
