Healthcare is changing as an outcome of artificial intelligence (AI), which is improving administrative, therapeutic, and diagnostic procedures. Data gathering, machine learning, deep learning, natural language processing, diagnostic systems, drug development, robots, wearable technology, ethics, trends, and future prospects are all explored in this study that explores AI's role in healthcare. It examines algorithmic developments, ethical issues, and data concerns. Emerging themes like personalised medicine and its regulatory ramifications are addressed in the paper. Promises made, issues including regulatory flaws, adoption reluctance, and interoperability still exist. This study provides a comprehensive understanding of artificial intelligence's revolutionary potential in healthcare, assisting scholars, practitioners, and legislators in making well-informed decisions and spurring innovation.
