Dogs Can Detect Cancer

Man’s best friend may also be a lifesaver – as a weapon in detecting cancer.
Odours given off by bowel cancer have been sniffed out by a specially trained dog with a 98% accuracy.
One Labrador in a Japanese study identified the disease in 33 out of 36 breath samples and 37out of 38 stool tests.
And it was most successful when the disease was in the early stages – a crucial time for treatment.
Dogs are able to detect volatile organic compounds which flag up the presence of cancer.
Using dogs would be impractical and costly but a sensor could be developed.
