Abstract	The healthcare sector generates enormous volumes of sensitive patient data through electronic health records, medical imaging systems, wearable devices, genomic databases, and clinical information systems. These data resources have significant potential to support advanced healthcare analytics, disease prediction, personalized medicine, and intelligent clinical decision-making. However, concerns regarding patient privacy, data security, regulatory compliance, and institutional data-sharing restrictions often limit the effective utilization of healthcare data. Traditional centralized machine learning approaches require data aggregation into a common repository, increasing privacy risks and regulatory challenges. Federated Learning (FL) has emerged as a promising privacy-preserving machine learning paradigm that enables collaborative model training without requiring raw data to leave local institutions. By allowing healthcare organizations to train shared models while maintaining local control over sensitive patient information, federated learning offers new opportunities for secure and scalable healthcare analytics. This study investigates federated learning for privacy-preserving healthcare analytics, focusing on implementation challenges, opportunities, and future research directions. The research examines federated learning architectures, privacy-preserving techniques, healthcare applications, security mechanisms, communication efficiency strategies, regulatory considerations, and model optimization approaches. Furthermore, the study evaluates practical implementation barriers, technological innovations, and emerging trends influencing the adoption of federated healthcare analytics systems. A descriptive and analytical research methodology supported by questionnaire surveys, case study evaluation, comparative analysis, and secondary literature review has been adopted. Findings indicate that federated learning significantly enhances privacy protection, promotes collaborative medical research, improves predictive modeling capabilities, and supports regulatory compliance. However, challenges related to data heterogeneity, communication overhead, model security, scalability, and interoperability continue to affect implementation effectiveness. The study concludes that federated learning represents a transformative approach to privacy-preserving healthcare analytics and is expected to play a critical role in the future of intelligent healthcare systems.
