Google developing cancer detector

Google now is looking to make a big impact in health care. Its research unit is developing a technology that uses pills containing nanoparticles and sensors worn on the wrist to detect diseases sooner.

The project, still in an early stage, would be based on detecting changes in a person's biochemistry as an early warning system.

Nanoparticles contained in pills would be able to explore the body at molecular and cellular levels and communicate to the sensor any changes that could suggest the development of cancer or an increasing risk of heart attack or stroke.

"What we are trying to do is change medicine from reactive and transactional to proactive and preventative," said Dr. Andrew Conrad, a molecular biologist heading up the research project.

While some experts have suggested that such knowledge could raise a person's anxiety level and even lead to unnecessary treatments, Conrad said that what's being developed are prescriptive medical devices and that the patient-doctor relationship would be preserved.
