Big Tech will be both friend and foe to Big Pharma CGAThompson
An artificial intelligence system developed by Alphabet’s Google unit proved as good as expert radiologists at detecting which women had breast cancer based on screening mammograms and also showed promise at reducing errors, researchers in the United States and Britain reported on Jan. 1.
The study, published in the journal Nature, is the latest to show that artificial intelligence has the potential to improve the accuracy of screening for breast cancer, which affects one in eight women globally. The findings of the study, developed with Alphabet’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 programme 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 U.S.-based group and by 1.2% in the British group. It also cut the number of false negatives, where tests are wrongly classified as normal, by 9.4% in the U.S. group, and by 2.7% in the British group.
