The evidence just keeps mounting that ordinary dogs can be trained to use their noses to detect various kinds of cancer with near-perfect accuracy — better than any standard test for the disease.
Moreover, the dog was equally good at sniffing out samples from patients with early-stage cancers as with advanced malignancies
Some scientists are trying to find out using chromatography and mass spectroscopy, which can detect trace amounts of chemicals in a sample. (A dog's nose can reportedly discriminate at the parts-per-trillion level.) They hope to one day build an electronic nose as good as a dog's.
The animal's ability to detect cancer from breath was 95% accurate overall, and 98% accurate from stools.
The current NHS screening programme uses a faecal occult blood test, which detects minute amounts of blood in stools - a sign of bowel cancer.
But researchers behind the latest study say this only picks up one in 10 cases of early stage bowel cancer.
If cancer could be detected early, the recovery rate could be higher

IME, dogs do just about everything better than humans.
But I'll bet you're right. It just wouldn't do to have everyone's cancer detected in the early stages. That would take a big bite out of the medical profit in this country.
