Abstract	Machine Learning (ML), a core branch of Artificial Intelligence (AI), has emerged as a transformative technology in modern healthcare by enabling intelligent diagnostics, predictive analytics, precision medicine, and personalized treatment planning. The growing availability of electronic health records (EHRs), medical imaging, genomic data, wearable devices, and real-time health monitoring systems has created unprecedented opportunities for developing data-driven healthcare solutions. Machine learning algorithms—including supervised, unsupervised, reinforcement, and deep learning models—are increasingly employed to detect diseases, predict clinical outcomes, identify high-risk patients, optimize treatment strategies, and improve healthcare resource management. These intelligent systems support clinicians in making accurate, timely, and evidence-based decisions while enhancing patient-centered care. This study examines the applications of machine learning in healthcare diagnostics and personalized medicine using a multidisciplinary perspective. Employing a qualitative and analytical research methodology based on secondary data from medical informatics, computer science, biomedical engineering, genomics, public health, and healthcare management literature, the study explores machine learning techniques, diagnostic applications, personalized treatment approaches, implementation challenges, ethical considerations, and future research directions. Particular emphasis is placed on explainable artificial intelligence (XAI), clinical decision support systems, predictive analytics, precision medicine, digital health, and responsible AI governance. The findings indicate that machine learning significantly improves diagnostic accuracy, early disease detection, treatment personalization, healthcare efficiency, and clinical decision-making while reducing diagnostic errors and supporting preventive medicine. However, successful implementation requires high-quality healthcare data, transparent AI models, interoperability, regulatory compliance, cybersecurity, patient privacy protection, and multidisciplinary collaboration between clinicians, data scientists, and policymakers. The study concludes that machine learning will play a central role in shaping the future of intelligent healthcare by enabling precision diagnostics, personalized therapies, and sustainable digital health ecosystems.
