Introduction: Breast cancer is considered a chronic degenerative disease, which leads to new knowledge about the root causes in order to combat this disease, and therefore it has been determined that the most important cornerstone in reducing this problem is prevention and early detection, as early detection determines appropriate diagnosis and treatment with High probability of cure but if performed late, curative treatment is unlikely to be offered since women diagnosed at advanced stages, to improve their health and quality of life, are assigned surgical treatment of choice, such as lumpectomy, quadruple resection, resection Simple breast, modified radical mastectomy, and radical mastectomy. Aim: This paper aims to study postoperative outcomes of breast cancer surgery of Iraqi patients. Patients and methods: In this study, a descriptive cross-sectional study was applied to study the postoperative outcomes of breast cancer surgery of Iraqi patients from 8th June 2021 to 5th August 2022. Data were collected for 130 patients from different hospitals in Iraq, where the patients were divided into two groups, the first group of patients, which included Harmonic focus surgery, which included 70, and the second group, the Monopolar electrocautery surgery, which included patients which include (60) patients. A statistical study was conducted for patients with osteoporosis using the SPSS program. Results and Discussion: Breast cancer is a chronic degenerative disease, and by its nature, it requires that women receive multimodal treatment, such as surgery, to control it, which exposes them to many risks that lead to postoperative complications. Learning to live with breast cancer that won't go away can itself cause some uncertainty, and this was shown by previous studies in Peru; a study conducted at the National Institute of Oncology indicated that 18% of patients with Cancers see the quality of life at a good level, 60% reported a regular level, describing their experience as not very effective in the personal sphere, 22% stated. According to the results, the characteristics of pain, weakness, fatigue, and irritability are noted. Likewise, they have memory problems and perceive that the treatment has affected their social life. Conclusion: This study found that Monopolar electrocautery surgery outperformed Harmonic focus surgery in numerous intraoperative and postoperative parameters, including operational duration, blood loss, drain volume, and length of drain placement, in patients who had neoadjuvant CTH before BCS. In contrast, this study demonstrated no significant difference in the incidence of postoperative seroma and associated complications between Harmonic Focus and monopolar electrocautery.
