AI detects breast tumors that are 27% more aggressive
Results from the largest-scale experiment of AI-powered breast cancer screening were recently released by Swedish researchers, who found that the system reduces radiologists' workload by almost half while increasing the percentage of cancers that radiologists can detect.

The specifics:

In order to determine whether AI could detect tumors that routine screening overlooks in between visits, the two-year study followed over 100,000 women.

The AI increased the detection rate from 74% to 81% without raising false positives by analyzing mammograms and flagging high-risk patients for radiologists.

When compared to conventional screening alone, women in the AI group had 21% fewer big tumors and 27% fewer dangerous tumor types.

By managing initial screening, sorting, and freeing up physicians to concentrate on the situations that require the greatest care, the technology also reduced the burden of radiologists by 44%.

AI is rapidly emerging as one of the most significant instruments in the battle against cancer, with applications ranging from drug development to tumor identification and treatment planning. Scaling this kind of early diagnosis by AI could change the lives of women worldwide, as over 2 million cases of breast cancer are diagnosed each year.
