But white can\u00a0be infection, inflammation or precancer. That&#8217;s why it&#8217;s so difficult to interpret with the human eye.&#8217;\u00a0<\/p>\n<p class=\"mol-para-with-font\"> A 2003 study <\/a>found the test was about 80 percent accurate in correctly identifying those with the disease as positive.\u00a0<\/p>\n<p class=\"mol-para-with-font\">To train the algorithm, the team recruited more than 9,400 women from Costa Rica between ages 18 and 94 years.<\/p>\n<p class=\"mol-para-with-font\">More than 60,000 images were taken during cervical cancer screenings between 1993 and 2000 and the woman were monitored over an 18-year period.<\/p>\n<ul class=\"rotator-panels link-bogr1 linkro-ccox\">\n<li>\n<p>  <span>AI could detect heart disease faster, earlier and cheaper&#8230;<\/span><\/p>\n<p><\/a><\/p>\n<p>  <span>New AI helps doctors predict and prevent life-threatening&#8230;<\/span><\/p>\n<p><\/a><\/p>\n<\/li>\n<\/ul>\n<p class=\"mol-para-with-font\">The team digitized the photographs and then trained the algorithm to recognize which cervical changes needed treatment and which didn&#8217;t need it for the new method called automated visual evaluation.\u00a0<\/p>\n<p class=\"mol-para-with-font\">&#8216;First you get [the algorithm] to recognize the cervix,&#8217; senior author Dr Mark Schiffman of NCI&#8217;s Division of Cancer Epidemiology and Genetics, told DailyMail.com.<\/p>\n<p class=\"mol-para-with-font\">&#8216;You take 80 percent of the bad and the good and train it to identify &#8220;this&#8221; is bad and &#8220;this&#8221; isn&#8217;t bad. Then you take an independent 20 percent not related and see if it can tell the difference.&#8217;\u00a0\u00a0\u00a0<\/p>\n<p class=\"mol-para-with-font\">The team used a statistical model to quantify its results called area under the curve. An AUC of 0.5 means it&#8217;s about the same as guessing and an AUC of 1.0 means perfect accuracy.<\/p>\n<p class=\"mol-para-with-font\">The AI tool, when identifying precancer, achieved an AUC of 0.91, about 1.3 times better than the review of human experts, which achieved an AUC of 0.69.\u00a0<\/p>\n<p class=\"mol-para-with-font\">Pap tests also performed worse, achieving an AUC of 0.71.<\/p>\n<p class=\"mol-para-with-font\"><span>&#8216;With a human expert, it&#8217;s open to interpretation and, even though the brain is good at detecting patterns, the neural networks are better,&#8217; said Loukissas.\u00a0<\/span><\/p>\n<p class=\"mol-para-with-font\">&#8216;It would make screening and triage more cost-effective in places where they currently aren&#8217;t.&#8217;\u00a0\u00a0\u00a0<\/p>\n<p class=\"mol-para-with-font\">For the future, the researchers hope to put the program onto a cellphone so that any woman in any country would be able to take a photo of their cervix and get their results back quickly.\u00a0\u00a0\u00a0<\/p>\n<p class=\"mol-para-with-font\">&#8216;Cervical cancer has become a  health disparity issue,&#8217; said Dr Schiffman.<\/p>\n<p class=\"mol-para-with-font\">&#8216;In Malawi, five percent of women get cervical cancer in their lifetime. In the US, it&#8217;s one-tenth of that.<\/p>\n<p class=\"mol-para-with-font\">&#8216;So we have something very simple, very inexpensive that can go anywhere where the HPV vaccine is not reaching people and where good testing isn&#8217;t reaching people.&#8217;\u00a0<\/p>\n<p class=\"mol-para-with-font\">The study comes on the heels of a growing body of research that has found that artificial intelligence can improve upon the work of physicians.\u00a0<\/p>\n<p class=\"mol-para-with-font\">This week, two separate studies from\u00a0the Mayo Clinic and Stanford University found that AI was able to identify irregular heart rhythms and the early stages of heart failure.<\/p>\n<p class=\"mol-para-with-font\">In some cases, the AI model did so up to 15 percent more accurately than EKG results analyzed by board-certified cardiologists.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Artificial intelligence could detect the start of cervical cancer in women better than trained doctors, a new study claims.
