Breast cancer is a widely recognized health concern, yet the concept of 'intrapersonalconflict' within the context of breast cancer treatment is relatively underexplored. While existing research predominantly addresses the impact of a breast cancer diagnosis on everyday life, there is limited investigation into the decisional and intrapersonal conflicts that women face during the course of their treatment. This qualitative study employs transcendental phenomenological analysis to examine these conflicts and the broader experiences of women as they navigate treatment decisions, lifestyle adjustments, and relational dynamics throughout their breast cancer journey. The study participants comprised 12 women aged between 21 and 80, all of whom had completed their breast cancer treatment at least one year before participating in this research. The analysis revealed that the women in this study experienced significant decisional and intrapersonal conflicts in relation to selecting treatment options, adapting to lifestyle changes, and managing shifts in personal relationships. Participants also reported encountering a wide range of physical, emotional, social, and psychological challenges throughout their treatment and recovery. A notable finding from this study is that the effects of these conflicts and challenges may persist well beyond the completion of treatment, indicating a need for sustained support and resources for survivors.
