The scientists from Microsoft proved that even 39% of cancer diagnoses could be detected even a year earlier. 

Many of you wonder how researchers from Microsoft are connected with the early detection of the cancer? 

Search history in the Bing search engine is an answer to this question. Researchers searched, amongst entries used by people already associated with cancer, for phrases connected with the disease. These phrases include previous enquiries about symptoms of the illness, for example pain in the chest.

Moreover, basing on data concerning the location of the given group ,they made an assessment whether the users can be exposed to factors increasing the risk of the cancer morbidity rate. 

Such analysis can be helpful in detecting the early stages of cancer. 

The good example can be a work published in 2009 by Google. In this work the early detection of a flu epidemic was being considered,  based on the  analysis of phrases used in the search engine. 

The huge success of Microsoft in 2013 was finding early evidence for the undesirable reaction to certain medicine, based on phrases used in the search engine.
