Just over two years ago, IBM's supercomputer Watson appeared on television to trounce expert quiz show contestants on "Jeopardy!" Now, doctors are looking to Watson for answers. The Maine Center for Cancer Medicine is one of two medical groups chosen to test Watson's lightning-quick computing power in an effort to improve care for cancer patients. Along with New York's Westmed Medical Group, doctors in Maine are "teaching" the supercomputer how to interpret clinical information to diagnose lung cancer patients and recommend treatment.
