Purpose: The purpose of this study was to understand and describe the experiences of stomach cancer patients in South Korea. Methods: Secondary analysis of qualitative data was designed. The data were analyzed via the Phenomenological Method, using the data of 12 stomach cancer patients, from the original data collected by narrative interviews in 2013. Results: Seven theme clusters emerged from the analysis. Beginning with: ‘Facing Life Threats from Cancer,’ this describes how the participants experience between cancer diagnosis and treatments. ‘Crossing the Boundary between Life and Death’ deals with desperate struggle to overcome medical treatments, such as gastrectomy and chemotherapy, while ‘Adjusting to Weakened Body’ illustrates the continuous daily struggle to follow dietary treatments after operation. ‘Dilemmas in Interpersonal Relationships’ illustrates the sensitivity of relationships from the cancer stigma, with predicaments rising in collective dining situations. ‘Encountering: Hidden Me, Inside Me’ describes changes in values of life and a matured self. ‘Supporters for Hope’ illustrates driving forces to keep hope alive in everyday lives. Lastly, ‘Happiness of Everyday Life Rescued from Misery’ describes how life turned into blessings from cancer after all. Conclusion: The results of this study would help oncology professionals to develop patient-centered cancer survivorship interventions, by understanding and gaining insights about the lived experience of stomach cancer patients.
