Microsoft analyzes web searches, finds clues for early cancer detection

Analyzing online activities can provide clues as to a person's chances of having cancer, Microsoft researchers showed in a paper published this week.

Specifically, the researchers demonstrated that by analyzing web query logs they were able to identify internet users who had pancreatic cancer even before they'd been diagnosed. The research is part of a larger trend where data analytics is being used to improve healthcare.

The study suggest that "low-cost, high-coverage surveillance systems" can be created to passively observe search behavior and to provide early warning for pancreatic cancer, and with extension of the methodology, for other challenging cancers," the researchers concluded. "Surveillance systems could also provide for automated capture and summarization of data and landmarks over time so as to provide patients with talking points in their discussion with medical professionals."
