description: <b>Summary</b><br> This metadata record provides details of the data supporting the claims of the related article: “The impact of lymphedema on health-related quality of life up to 10 years after breast cancer treatment”. The related study investigated the impact of breast cancer-related lymphedema (BCRL) on health-related quality of life (HRQoL) up to 10 years after breast cancer treatment. Type of data: HRQoL evaluated with the Lymphedema Functioning, Disability and Health Questionnaire, the Disabilities of the Arm, Shoulder and Hand Questionnaire and the Short Form (36) Health Survey Questionnaire. Subject of data: <i>Homo sapiens</i> Sample size: 856 (213 with BCRL, 643 without BCRL). Population characteristics: The study participants comprised breast cancer patients treated with axillary lymph node dissection with and without BCRL. All patients were treated for breast cancer between 1 Jan 2007 and 31 Dec 2017 in the region of southern Denmark (current population approximately 1.2 million). Follow up and assessments of all patients was conducted between 1 Jan 2019 and May 2020. Recruitment: Baseline variables and data regarding breast cancer treatment were prospectively registered in the National Breast Cancer Registry from the Danish Breast Cancer Cooperative Group (DBCG), which was retrieved for this study. The DBCG include more than 95% of breast cancer patients in Denmark, and all breast cancer centres in Denmark follow the same treatment protocols regardless of geographic region. Identified patients were recruited in the outpatient clinic and sent questionnaires using REDCap. <b>Data access</b> The majority of data are contained in the STATA file ‘workfile_alldata.dta’, while the Excel spreadsheet ‘inclusion flowchart - key numbers.xlsx’ contains some of the data underlying Figure 1. These data files are housed on institutional storage and are not publicly available for the following reason: data contain information that could compromise research participant privacy. However, the data can be made available upon reasonable request to either of the corresponding authors, in accordance with Odense University Hospital and the Region of Southern Denmark’s data sharing policy as part of an external collaborative request. The individual-level data are not publicly available because of data privacy regulations and restrictions for use of such data, as stated in the study protocol and patient consent form. <b>Corresponding author(s) for this study</b> Mads Gustaf Jørgensen, MD, Department of Plastic Surgery, Odense University Hospital, J.
