Abstract

AI isn’t just a buzzword in healthcare anymore—it’s changing the game everywhere, from diagnostics and treatment to how hospitals run day-to-day. This review digs into what’s happening right now with AI in medicine. We look at everything from radiology and oncology to surgery, cardiology, and even medical education. The big upsides? More accurate diagnoses, faster workflows, and better patient outcomes. But there’s a flip side: data privacy worries, bias in algorithms, tricky regulations, and some doctors who just aren’t convinced yet. Real-world stories highlight how AI is catching cancer earlier, predicting heart problems before they happen, making surgery safer, and even helping out during pandemics. We also compare how India, the US, and Europe are jumping on the AI bandwagon. Looking ahead, the focus is on making AI more understandable, combining different data types, keeping things ethical, and getting people working together across borders. Bottom line: if we roll this out the right way, AI can really boost what doctors do and help transform healthcare for everyone.
