In Europe, women aged 50 to 69 are advised to get a mammogram every two years, with the resulting scan analysed by two radiologists.</p><p>The study in Sweden involved the scans of 80,000 women who had mammograms at four sites in southwest Sweden between April 2021 and July last year.</p><figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=2744607" width="100%"></iframe></figure><div class="iwantbar">Watch more News on <a href="https://www.iwanttfc.com/#!/browse/Genres/News/tag_id_genres/id_news" target="_blank">iWantTFC</a></div><div><strong> &#x27;Considerable importance&#x27; </strong></div><p>Their scans were randomly divided for analysis to either an AI-supported system or two human radiologists, who served as the control group.</p><p>The AI algorithm read the scans and predicted the risk of cancer out of 10.
