This descriptive phenomenological study was conducted to explore the lived experiences for supportive care needs of women with breast cancer-related lymphedema. Purposive sampling was used to recruit participants. In-depth, semi-structured interviews were conducted to collect data. Thematic analysis method was used for data analysis. Data saturation was achieved after interviewing 19 participants. The study was divided into four main themes and nine subthemes: physical (caused by difficulties in performing household chores, limitations in performing self-care activities, and challenges in shopping), psychosocial (being addicted to someone else in daily life, uncertainty about the future, social, and religious support), healthcare systems and information (attention from healthcare professionals, education and lifestyle advices, and access to healthcare sources), and financial supportive care needs. Women experience various SCNs in their daily lives. Provision of supportive care from both family members or others and healthcare professionals could ease the daily lives, improve physical, and psychosocial well-being.
