The use of artificial intelligence in breast cancer screening reduces the rate of a cancer diagnosis by 12% in subsequent years and leads to a higher rate of early detection, according to the first trial of its kind. Researchers said the study was the largest to date looking at AI use in cancer screening. It involved 100,000 women in Sweden who were part of mammography screening and were randomly assigned to either AI-supported screening or to a standard reading by two radiologists between April 2021 and December 2022. Mammography screening supported by AI reduced cancer diagnoses in the years after a breast screening appointment by 12%, according to the research, published in The Lancet. Although the study showed the apparent benefits AI could bring to mammography screening, the researchers do not support replacing healthcare professionals with AI, as screening still requires at least one human radiologist to perform the reading with AI support.
