This study explores the experience of nursing a subject with reoccurring breast cancer who is fearing death. Adopting the Gordon 11 Function Health Patterns from July 16th, 2017 to July 22nd, 2017, this study collected data through observation, interviews, and physical assessments, and it was confirmed that the nursing problems of the subject included acute pain, fear of death, and an ineffective family coping strategy. In the care process, individual care measures were provided, and techniques for controlling pain were taught. Meanwhile, the establishment of a therapeutic interpersonal relationship with an empathic attitude prompted the subject to share her inner fear. The religious belief and family support were also encouraged, and under the guidance and companionship of nursing staffs the psychological counseling, briefings of successful cases and conversations helped the subject enhance her confidence through learning about the experiences of others, thus reducing her fear of death. Family meetings were arranged to establish an effective communication model, increase mutual understanding, and enhancing her family coping capabilities. The subject and the medical team established a common goal to improve the quality of the subject’s life and help the subject face the disease. Through this care experience, the author deeply understands that family support and mental comfort are very important. This study suggests that competent authorities strengthen the assessment accuracy and handling capabilities for mental aspects, so as to fully exert the unique functions of nursing, as well as to perfect holistic health care. In recent years, the development of genetic testing for breast cancer has become increasingly mature, but the fact that this high-cost self-pay testing cannot be popularized among high-risk groups is a major limitation. This study hopes that effective support measures can be added to the National Health Insurance policy, so that preventive medicine can be implemented to reduce the trend and incidence of breast cancer occurring at younger ages.
