Currently, two radiologists are required to review the images from each screening to ensure accuracy. However, it is hoped the AI being trialled will enable one of the speciality doctors to complete the process, freeing up radiologists to see more patients and, in turn, cut waiting lists. More than two million mammograms a year are carried out under the screening programme, so it could have a major impact on the workload of radiologists. Department of Health and Social Care chief scientific adviser Prof Lucy Chappell said the study could lead to a "significant step forward". Health Secretary Wes Streeting said this should just be the start of a wider improvement in cancer care.
