Artificial Intelligence (AI) has emerged as one of the most influential technologies in modern healthcare. The integration of AI into medicine has introduced new possibilities for disease diagnosis, personalized treatment, medical research, and improvement of patient care systems. AI-based technologies can analyze large amounts of medical data, identify patterns, and support healthcare professionals in making accurate decisions. This paper discusses the role of artificial intelligence in healthcare, its applications in diagnosis and treatment, benefits, challenges, and future perspectives. Although AI provides significant advantages, ethical concerns, data privacy issues, and the need for human supervision remain important considerations. The future of healthcare is expected to involve collaboration between medical professionals and intelligent technologies to provide safer and more effective medical services.
