Highly Trained Dogs Detect Breast Cancer from Bandage
Researchers developed a technique that is inexpensive, simple and non-invasive, that can accurately detect breast cancer. It involves a highly-trained dog that is able to sniff out breast cancer from a piece of cloth which had touched the breast of a woman with a tumour.
Working on the assumption that breast cancer cells have a distinguishing smell which sensitive dog noses will pick up, the team collected samples from 31 cancer patients.

With the help of canine specialist, researchers trained German Shepherds Thor and Nykios to recognise cancerous rags from non-cancerous ones. After six months, the dogs were put to the test over several days in January and February this year.
This time, the researchers used 31 bandages from different cancer patients than those the dogs had been trained on.
One bandage was used per experiment, along with three samples from women with no cancer.
On the second try, they scored 100 percent—sitting down in front of the box containing the cancerous sample with their muzzle pressed deep into the cone.
’There is technology that works very well, but sometimes simpler things, more obvious things, can also help,’ said Amaury Martin of the Curie Institute. ’Our aim was see if we can move from conventional wisdom to... real science, with all the clinical and research validation that this entails.’
The research team believes that one day dogs may be replaced by ’sniffing’ machines, possibly armies of electronic diagnosticians dedicated to analysing samples that people far from clinics would send them by the post.
"In these countries, there are oncologists, there are surgeons, but in rural areas often there is limited access to diagnostics," Isabelle Fromantin, who leads project Kdog, told journalists in Paris. In France, the chances of surviving ten years after a breast cancer diagnosis is about 85 percent, compared to around 50 percent in poorer countries.
