Study shows cancer-sniffing ability of dogs
LONDON British researchers have released a study suggesting dogs are able to smell cancer in humans.Scientists at an English hospital tested six dogs. They used urine samples from 36 bladder cancer patients as well as over 100 cancer-free people.
Each dog would sniff seven urine samples and sit down next to the one from a bladder cancer patient.
The dogs picked the right sample over 40 percent of the time. The success rate of just guessing would be 14 percent.
Experts say it's unlikely that dogs will be involved in cancer detection any time soon. But they call the results promising.
The study appears in this week's British Medical Journal.
