removing a small sample of body tissue and sending it for further tests. here at aberdeen royal infirmary, june's scan has been reviewed by ai software as well as human clinicians. dr gerald lipp demonstrates the process using anonymised scans. so what we are seeing now, we have a lady who has mammograms on her left side and right side, you are looking for differences. there is a lesion in the left breast here, and of course this is something you would expect a human being — you canjust tell there is something different in the pictures there, and if you click on this ai button, it circles an area to check. but the main area of most concern is this area circled here, where the cancer is on the left side. in screening, you want to pick up things that are small before they become big. programmes like this one identify breast cancer in roughly 6 in 1000 women.
