摘要:Introduction: The prevalence of breast cancer among women in compare to other types of cancers in all over the world and in Iran is high. Mastectomy surgery is one of the common treatments for these patients. Another method, which is less invasive, is Lumpectomy. This study comprised the satisfaction of patients under two types of surgery; Mastectomy and Lumpectomy. Materials and Methods: In this cross-sectional study, two types of patients which had either, Mastectomy or Lumpectomy, were studied. Results: From 119 patients which studied here, 80 patients (66.7%) were treated by mastectomy and 39 patients (32.5%) were treated under lumpectomy. Two groups had not significant differences in duration between diagnostic and surgery, the number of lymph nodes involved and the number of lymph nodes removed. Lumpectomy patients had higher pain and numbness in 24 h, 1 week after surgery and at the time of study than the other group. The observed difference was significant ( P = 0.043). Discussion: It is implied in previous studies that patients under lumpectomy had more satisfaction than patients under mastectomy. However, no differences were observed in quality-of-life between the two groups in some other studies. The differences between various studies might be for the sake of cultural variety and time interval between surgery and filling questionnaire.
