This paper took the “see your life story” - volunteer service project of the cancer patient care program of the First Affiliated Hospital of Guangzhou Medical University as an example， and explored the application of life narrative in the care service of cancer patients. The project adopted the multi-dimensional volunteer service model of “doctors and nurses + volunteers + social workers + patient friends”，used the life narrative method， and guided the three groups of cancer patients， patient caregivers， and oncology medical staff to tell their life stories through medical volunteers. Finally， these life stories were delivered in diversified ways， such as physical picture books， interview stories， and sharing meetings. The connection between patients can be promoted in the form of sharing， so that patients and caregivers can get support， and truly achieve to impact life with life. This paper selected the cases in life story books， deeply analyzed the important role of life narrative in promoting the physical and mental recovery of cancer patients， as well as provided reference suggestions for improving patients’medical experience and promoting the cultural development of public hospitals.
