The theory that dogs can smell cancer is scientifically supported, reported the British Medical Journal.

The report is from an experiment conducted by researchers at Amersham Hospital in Oxford, England. The experiment involved six dogs that were trained to distinguish between urine from patients with bladder cancer and urine from healthy subjects.

The dogs successfully identified the sample from a cancer patient 41 percent of the time. The ability to identify the correct sample by chance alone is only 14 percent. The success rate would improve, the report concluded, if training methods were more fully developed.
