Dogs can detect cancer

Scientists hope to develop a special electronic nose like a dog's nose to detect cancer in the future.

Two three-year-old Labrador retrievers were trained to detect prostate cancer through volatile organic compounds at the Military Veterinary Center of the Italian Ministry of Defense, Mother Nature Network reported.

As a result, after sniffing 400 urine samples, one dog detected prostate cancer with 100% accuracy, while the second dog was 98.6%.

Not only prostate cancer, dogs can also sniff out many other cancers such as breast, ovarian, colon, bladder, skin and lung cancer.

Cancer causes the patient's body to release a special organic substance, and dogs can sense it but humans cannot. With 220 million olfactory cells in their noses, dogs' ability to detect odors is millions of times higher than humans.

Many owners tell stories of their dogs acting strangely, constantly sniffing or sniffing an area of ​​their body, only to find out at a vet that the area contained a tumor.

From the research results, scientists hope to develop a special electronic nose, as sensitive as a dog's nose, to detect cancer in the future.
