Data for the Spanish adaptation of Breast Cancer and Lymphedema Symptom Experience Index (BCLE SEI Esp).

Breast cancer is one of the most diagnosed cancer in women worldwide and lymphedema is one of the most common late and chronic adverse effects of breast cancer treatment. Lymphedema symptoms are essential signs of early-stage of lymphedema as they often precede changes in limb size or girth or a lymphedema diagnosis. Therefore, to achieve early detection and prevent lymphedema progression, it is important to promote patient selfcare in terms of the awareness symptoms identification. To this purpose Breast Cancer and Lymphedema Symptom Experience Index (BCLE SEI Esp) scale was used. Between October 2018 and June 2020, we collected data from 286 lymphedema and non-lymphedema patients post-breast cancer treatment on sociodemographic information, lymphedema symptoms, daily living-function and psychosocial distress, women and the data comparison between lymphedema and non-lymphedema patients were provided in this publication. This dataset can be used as a reference in clinical settings or in clinical studies or as an instructional tool to teach breast cancer patients and clinicians to be aware of lymphedema symptoms and to help clinicians and patients to achieve early identification of lymphedema symptoms and the impacts of lymphedema symptoms in women´s life and to develop future research, for example, to develop predictive algorithms.
