Turkish Version of Breast Edema Questionnare: Validity and Reliability Study

This study was planned to investigate the complaint of breast edema after breast conserving surgery and radiotherapy, which are considered as the main treatment modalities for breast cancer. The incidence of breast edema after these treatments ranges from 0% to 90.4%. In contrast to arm lymphedema, which has been described in detail in the literature, only a few studies have investigated breast edema. There is no survey study that comprehensively examines the presence of lymphedema and its clinical features (duration, severity, location). Studies to assess breast edema after breast cancer treatment have revealed the need for a condition-specific scale. Therefore, the "Breast Edema Questionnaire" was developed to assess breast edema in women who have undergone breast cancer surgery. The original language of this questionnaire is German and its reliability and validity has not been studied in another language. In this study, the validity and reliability of this questionnaire, which specifically assesses breast edema, will be tested in Turkish women.
