Doctors in Hungary are testing the effectiveness of AI software for spotting cancer, including breast cancer. Early results show that AI systems are at least as capable as radiologists at detecting cancer, and Hungary has become one of the largest testing grounds for the technology on real patients. Clinics and hospitals in the US, UK, and EU are also beginning to test or provide data to help develop the systems. However, there are still many obstacles to overcome before the technology can be more widely adopted. Additional clinical trials are needed to show the tool can produce accurate results on women of all ages, ethnicities, and body types, and can cut down on false positives that are not cancerous. The technology has also sparked a debate over whether it will replace human radiologists, with makers of the technology facing regulatory scrutiny and resistance from some doctors and health institutions. However, many experts believe that the technology will only be effective if it is used in partnership with trained doctors.
