Dogs capable of detecting breast cancer in women's sweat A first clinical trial is launched with 450 women.

Can a dog really do it?


Will the human's best friend (the dog) save women from breast cancer? According to information from Le Parisien, the Institut Curie has started the first clinical trial to detect this disease using sniffer dogs.
450 women, half of them healthy, are participating in this hopeful clinical trial, reports Friday, February 21
You may have heard of these sniffer dogs, able, thanks to their extraordinary flair, to detect the smell of a tumor in the sweat of these women.
We have been hearing about the dog medical program for a few years now. Two Malian shepherds, Thor and Nikios, have been training to recognize breast cancer since 2016.
But the project started even earlier, in 2009, when Isabelle Fromantin, a nurse at the Institut Curie, wrote a thesis on the wounds associated with breast cancer. It aimed to "establish a link between cancer and the smell of wounds," the KDOG project website says.
The problem is that this smell is undetectable by humans. This is where the idea comes from to use canine flair, "more efficient than chemical instruments".

Did it come true?

Today, the black labrador Nougaro has joined Nykios. These are the two mainstay dogs of the program. They will soon be followed by Odin, Oops, and Owen, whose training is not yet complete.
After six months of training between August 2016 and February 2017, the success rate of these dogs was 100%. Among 130 wipes, they correctly identified the 79 women who had just been diagnosed with breast cancer.
Today, researchers estimate that they can recognize a tumor in more than 90% of cases. But we must now take the next step, recognizing the tumour before it is, for example, detected by a mammogram.
Although, beware, the researchers do not intend to replace this examination, it would be a kind of pre-test, mammography being sometimes difficult to perform, especially in geographically isolated areas or low-income countries.
"Now we have to move from proof of concept to method. The dog is capable, but is it able to do so consistently and repeatedly? This is what we have to demonstrate scientifically," Pierre Bauer, an engineer, and head of the dog project told Le Parisien. "There is no contact between the patient and the dog," he continued.

If this clinical test is successful, dogs could be trained to detect other cancers, such as ovarian or prostate cancers, from men's urine.
