Microsoft is searching for preventative measures to battle cancer with the help of itsmachine learning technology. Throughout the second half of the year, we’ve reported about Microsoft Research using search query and anonymized data to link potential risks, health symptoms, and the probability of diagnosis to pave a path for healthcare professionals.

With 20% of lung cancer diagnoses made in non-smokers, Microsoft Research is determined to assist in finding those nontraditional causes that are plaguing the population. They’ve used a similar algorithm to the research inPancreatic Cancer, noting that approximately 5 million anonymous searchers were examined in this particular study. Apparently, this model can identify 1.5% -40% people nearly a year in advance before they confirm a lung cancer diagnosis. Even though it’s been tweaked to prevent false positives, that’s still a significant amount of time that could potentially save a life.

Eric Horvitz, the Managing Director of Microsoft Research in Redmond, co-authored a publication forJAMA Oncologywith their findings.

The statistical classifier predicting the future appearance of landmark web queries based on search log signals identified searchers who later input queries consistent with a lung carcinoma diagnosis, with a true-positive rate ranging from 3% to 57% for false-positive rates ranging from 0.00001 to 0.001, respectively. The methods can be used to identify people at highest risk up to a year in advance of the inferred diagnosis time.

The results also explained that five key factors that were found to lead to lung cancer via search queries included family history, age, radon levels, primary location, and occupation. The reason that evidence of smoking wasn’t on the list? Because it’s hard to determine the user’s smoking preferences from just a search history.

Microsoft Research believes that these queries may not be able to find specific causes on its own. According to the blog post, it is the start of a hypothesis that can lead to more studies and researches in the healthcare industry.

For most of the kids of his age, the Internet was an amazing way to play and communicate with others, but he was deeply impressed by the flow of information and how easily you can find anything on the web.

Prior to founding Windows Report, this particular curiosity about digital content enabled him to grow a number of sites that helped hundreds of millions reach faster the answer they’re looking for.
