In 2020, an AI system developed by Google Health detected breast cancer in mammograms with greater accuracy than expert radiologists, reducing both false positives and false negatives. The system found cancers that six radiologists missed. This was not an isolated result. AI diagnostic tools have matched or exceeded specialist performance in detecting diabetic retinopathy, skin cancer, and certain lung conditions. At a hospital in India, an AI system screens thousands of chest X-rays daily, flagging tuberculosis cases in rural areas where radiologists are scarce. These systems do not replace doctors, they serve as a tireless second pair of eyes. The implications are staggering: earlier detection, fewer missed diagnoses, and healthcare access in regions with severe specialist shortages.
