Two patients receiving the same treatment for breast cancer may be entirely different in significant ways. One may be a marathon runner, the other a more sedate reader. One might be a smoker, while the other is considered a health nut. One may be in her 60s while the other just turned 40. With all these differences, these two women might need different cancer treatments. The challenges for scientists and doctors is in finding information about treatments for specific types of people. That critical information is lost in mountains of data, and doctors don't have the time – possibly years – it would take to sift through all of that data to find what they need.
