This study aimed to investigate how health-related quality of life changed from the time of diagnosis to 1 year after breast cancer surgery for the main surgical techniques.</p><p><strong>Methods: </strong>This prospective longitudinal single-centre study included patients with primary breast cancer diagnosed in 2019-2020 who underwent surgery. Patients completed a health-related quality of life questionnaire (Breast-Q) at baseline. One year after surgery, they completed the Breast-Q a second time, the EORTC (European Organization for Research and Treatment of Cancer) quality of life questionnaire-C30 and the quality of life questionnaire-BR23. Analysis of variance and Kruskal-Wallis tests were used to evaluate the differences in health-related quality of life between surgical groups.

Patients that had partial mastectomy or oncoplastic partial mastectomy were more satisfied with their breasts (P < 0.001), had a better body image (P = 0.006) and higher sexual functioning scores (P = 0.027) than patients who had a mastectomy with/without reconstruction.
