Introduction
Healthcare is one of the most essential pillars of human life. Over centuries, medical science has evolved from herbal remedies and basic surgical procedures to advanced pharmaceuticals, diagnostic imaging, and biotechnology. Yet today, healthcare systems worldwide face immense challenges: aging populations, rising healthcare costs, global pandemics, and shortages of skilled professionals.
Enter Artificial Intelligence (AI)—a game-changer in modern medicine. AI is not just assisting doctors; it is revolutionizing diagnostics, treatments, patient monitoring, hospital management, and drug discovery. By analyzing massive datasets, detecting patterns invisible to humans, and making real-time decisions, AI is transforming healthcare into a smarter, faster, and more personalized system.
This article explores in depth how AI is reshaping healthcare, including applications, benefits, challenges, case studies, and a vision of medicine by 2040.
