Scientists say Google's AI system can detect breast cancer faster and also reduces the number of false positive results
A yellow box indicates where an artificial intelligence system found cancer hiding inside breast tissue, in an undated photo released by Northwestern University in Chicago January 1, 2020.
The findings of the study, developed with Alphabet Inc's DeepMind AI unit, which merged with Google Health in September, represent a major advance in the potential for the early detection of breast cancer, Mozziyar Etemadi, one of its co-authors from Northwestern Medicine in Chicago, said. The study showed the AI system could identify cancers with a similar degree of accuracy to expert radiologists, while reducing the number of false positive results by 5.7% in the US-based group and by 1.2% in the British-based group.
Connie Lehman, chief of the breast imaging department at Harvard's Massachusetts General Hospital, said the results are in line with findings from several groups using AI to improve cancer detection in mammograms, including her own work. This has the potential to "exceed human capacity to identify subtle cues that the human eye and brain aren't able to perceive," Lehman added.
