Abstract: Objective The aim of this study was to conduct a bibliometric and visual analysis of the literature related to breast cancer caregivers,to understand the developmental trend of breast cancer caregivers,and to provide references for future research. Methods Relevant literatures about breast cancer caregivers were obtained by searching the Embase database.The Excel 2016 software was used to produce and publish histograms of different authors,institutions,countries and the frequency of keywords,and generate high-yield authors,high-yield institutions,high-yield countries and high-frequency keyword tables.The VOSviewer 1.6.15 software was used to extract the authors,countries,institutions and keywords to generate a network map of high-yield authors,institutions and high-frequency keywords clustering network. Results A total of 698 documents meeting the requirements were retrieved,and the number of researches showed an overall upward trend.The authors came from 63 countries and 1,350 institutions.The country with the largest number of articles was the United States.The most prominent institution was University of California.The author formed 5 cooperative groups,with less cooperation among different groups.The research topics of breast cancer caregivers were relatively concentrated,among which the quality of life,the burden of caregivers,and palliative treatment were the focus of researchers. Conclusion The burden of breast cancer caregivers has gradually attracted attention;however,there is a lack of researchers and groups who have been engaged in this research field for a long time.The breadth and depth of research need to be further strengthened.At the same time,the communication and cooperation between different groups need to be strengthened to jointly produce high-quality research.The life quality of breast cancer patients and their caregivers are improved to provide guidance.
