An intriguing new study published by researchers in Japan shows that dogs can be trained to detect certain types of cancers in humans by sniffing breath and. . poop!
Researchers have trained an 8 year old Labrador Retriever to detect the presence of colorectal cancer from breath or stool. The dog, named Marine, returned a 95 percent accuracy rate when sniffing breath, and a 98% accuracy rate for stool. In the study, Marine returned an overall accuracy rate of 91% of samples from cancer patients, and 99% accuracy rate from healthy test subjects.
Marine was trained at St. Sugar Cancer Sniffing Dog Training Center in Chiba, Japan. The tests were conducted at Fukuoka Dental College Medical and Dental Hospital and Arita Kyoritsu Hospital. The study represents another step towards the development of an early detection system for colorectal cancer.
Researchers also noted that Marine has been able to detect other cancers from breath sampling, including beast, lung, prostate, uterine, ovarian, bladder, gastric, pancreatic, esophageal, and bile-duct.
