TRANSFORMING HEALTHCARE WITH EMERGING TECHNOLOGIES: INTEGRATING AI, ML, XR, 6G, BIG DATA FOR PERSONALIZED MEDICINE AND PREDICTIVE CARE

This study presents a critical analysis of Health Data Science and its evolving role in transforming healthcare delivery through advanced computational methodologies. By systematically integrating machine learning (ML), big data analytics, the Internet of Things (IoT), and extended reality (XR), the research demonstrates how these technologies contribute to early diagnosis, personalized treatment, and clinical decision support across diverse medical domains such as oncology, cardiology, diabetes care, radiology, and public health. The manuscript examines specific applications including predictive modeling for disease progression, federated learning for privacy-preserving data sharing, and multimodal image fusion using deep neural networks. It evaluates model performance using key metrics such as AUC-ROC and F1-score, highlighting both improvements over traditional diagnostic methods and current limitations in generalizability and real-world deployment. Ethical, legal, and data governance challenges are also discussed, with recommendations for enhancing transparency, fairness, and interoperability in health data systems. Through interdisciplinary collaboration and rigorous data practices, Health Data Science has the potential to foster more responsive, equitable, and patient-centered healthcare solutions. This work contributes actionable insights for clinicians, developers, and policymakers striving to leverage data-driven innovations in clinical environments
