Circumference measurements for lymphedema The extremity volume will be calculated using the Frustum formula. Modified Constant Murley Score for shoulder and upper extremity loss of function and evaluation of activities of daily living, pectoralis major and pectoralis minor shortness tests, Tanita for body composition determination, L-Dex score for bioimpedance analysis, Functional Evaluation of Breast Cancer Treatment for functional status ( Functional Assessment of Cancer Therapy -Breast Cancer - FACT-B scale, Cancer Fatigue Scale for fatigue, 6 Minute Walk Test (6MWT) for cardiovascular endurance and Hospital Anxiety and Depression Scale (HAD) for psychosocial status will be used. All measurements will be repeated preoperatively (at least 3 days before the operation), on the 1st postoperative day and 3 months later.
At least 42 patients between the ages of 30-65, who were followed up in Pamukkale University General Surgery Breast Polyclinic and planned for breast surgery, will be included in the study. Those who met the criteria for inclusion in the study and those who voluntarily agreed to participate in the study, who were preoperatively evaluated, will be randomly divided into two groups using the closed envelope method by matching age, gender, type of surgery and breast cancer stage. The first of these groups is the study (n=21) and the second is the control group (n=21).
