Cancer-sniffing dogs

Scientists report that dogs can smell disease in the urine of bladder cancer patients. In the study, published in this week's British Medical Journal, the canines successfully identified a cancer patient's urine sample placed among six control samples 41 percent of the time, far better than the 14 percent expected by chance. From an Associated Press article on the research:

"Perhaps the most intriguing finding, though, was in a comparison patient whose urine was used during the training phase. All the dogs unequivocally identified that urine as a cancer case, even though screening tests before the experiment had shown no cancer. Doctors conducted more detailed tests on the patient and found a life-threatening tumor in the right kidney."
