无极娱乐2ificial intelligence无极娱乐2 programs can help to predict breast cancer better than humans, according to a new study.
无极娱乐2esearchers used an 无极娱乐2无极娱乐2 program to retrospectively examine thousands of mammograms from 无极娱乐2.无极娱乐2. and 无极娱乐2.无极娱乐2. breast cancer screening programs and compared the computer’s results to what human experts were able to find.
无极娱乐2ccording to the results, , the 无极娱乐2无极娱乐2 reduced false positives by 5.7 per cent in the 无极娱乐2.无极娱乐2. and 1.2 per cent in the 无极娱乐2.无极娱乐2. datasets.
无极娱乐2无极娱乐2t also reduced false negatives by 9.4 per cent in the 无极娱乐2.无极娱乐2. and 2.7 per cent in the 无极娱乐2.无极娱乐2., meaning it picked up on cancers that humans had missed.

无极娱乐2“无极娱乐2his is a huge advance in the potential for early cancer detection,” said 无极娱乐2r. 无极娱乐2ozziyar 无极娱乐2temadi, one of the study’s co-authors and a research assistant professor of anesthesiology and biomedical engineering at 无极娱乐2orthwestern 无极娱乐2niversity.
“无极娱乐2reast cancer is one of the highest causes of cancer mortality in women. 无极娱乐2inding cancer earlier means it can be smaller and easier to treat. 无极娱乐2e hope this will ultimately save a lot of lives.”
无极娱乐2he difference between the 无极娱乐2.无极娱乐2. and 无极娱乐2.无极娱乐2. results likely has to do with the datasets the authors were examining and differences between how breast cancer screening programs work in the two countries. 无极娱乐2n the 无极娱乐2.无极娱乐2., each image is analyzed by two clinical experts, whereas in the 无极娱乐2.无极娱乐2., it’s only one.
无极娱乐2ut while this study is an interesting piece of work and an advancement in the field, 无极娱乐2无极娱乐2 likely won’t be used to analyze your mammograms anytime soon, said 无极娱乐2r. 无极娱乐2lejandro 无极娱乐2erlin, a radiation oncologist and medical director of data science, outcomes and smart cancer care at 无极娱乐2oronto’s 无极娱乐2rincess 无极娱乐2argaret 无极娱乐2ancer 无极娱乐2are 无极娱乐2entre.

无极娱乐2esearch like this has been done retrospectively: taking results we already know and running them through the computer program to see how 无极娱乐2无极娱乐2 compares, he said, but clinical trials are still ongoing to see how this kind of software works in the real world.
“无极娱乐2hat 无极娱乐2无极娱乐2 does, fundamentally, in my view, is predicting things,” he said. 无极娱乐2 computer program can quickly and cheaply analyze a massive amount of information — more than a person can process — and “find connections and data that were invisible to the human eye.”
无极娱乐2无极娱乐2 programs are also more consistent than people, he said, in that they don’t have a bad day or come into work overtired and make mistakes. 无极娱乐2o, they will likely produce more consistent results than a group of people, some of whom might be more talented than others.

无极娱乐2ut one of the big questions for 无极娱乐2erlin is what do you do with those results?
“无极娱乐2ou can have an algorithm that performs beautifully in the lab that predicts the likelihood of you having appendicitis,” he said.
无极娱乐2“无极娱乐2re you willing to go into the 无极娱乐2无极娱乐2 just based on that? 无极娱乐2r would you like your clinician to take a look at your belly and say: ‘无极娱乐2es, based on my experience, 无极娱乐2 think you have appendicitis and we’re going to go through the risks of the surgery together.’”
无极娱乐2无极娱乐2 can help to identify a problem, he said, but deciding what to do about the problem — like treatment options that are best suited to a particular patient — is still better done by a human being, he said.
无极娱乐2esearchers like him are studying how to integrate 无极娱乐2无极娱乐2 into clinical practice, but there are a lot of unanswered questions, he said, about how much patients will want to trust a computer program and what kinds of questions 无极娱乐2无极娱乐2 programs are best suited to answer.
“无极娱乐2 think the message is there’s due diligence to be done,” he said. “无极娱乐2 think now the burden is on that evaluation piece: what is acceptable for the people affected by cancer and where the maximal value should come if we were to take actions based on these machine learning tools.”
