Background: Breast cancer remains the most common cancer among women in Qatar, with a high mortality rate partly attributed to low participation in breast cancer screening (BCS). Nursing practice in Qatar operates within hierarchical healthcare structures that often marginalize nurses' knowledge and limit their autonomy, impacting their ability to contribute to breast health promotion.Aim: To explore how postmodern feminist perspectives can address the marginalization of nurses' knowledge and contributions within breast screening practices in Qatar.Methods: A philosophical inquiry using postmodern feminist analysis was conducted, drawing on a case study of breast screening practices in Qatar. The study compared two paradigmatic perspectives: logical positivism and postmodern feminism.Results: The findings highlight systemic barriers limiting nurses' roles in breast health education and advocacy. Logical positivism, with its emphasis on measurable outcomes, reinforces hierarchical power structures, while postmodern feminism advocates for inclusive, context-sensitive approaches to nursing practice. This analysis demonstrates how empowering nurses through a postmodern feminist framework can enhance their contributions to patient care and health promotion.Conclusions: Adopting a postmodern feminist perspective enables a reevaluation of nursing practice, emphasizing the value of nurses' knowledge and advocating for collaborative healthcare models. These findings suggest the need for policy changes to support nurses' autonomy and expand their roles in breast health promotion, particularly in culturally sensitive contexts like Qatar.Implications for Profession and/or Patient CareEmpowering nurses in Qatar could improve participation in breast screening by fostering trust and enhancing patient education. This shift would enable nurses to engage more actively in health promotion and patient advocacy.
