Dog having super smelling power can detect cancer colon from the smell of stool.
Dog Snout May Be Colon Cancer Screening Tool
Canine scent detection may be an effective means of screening for colorectal cancer, researchers say.
Using colonoscopy as a reference, a Labrador retriever sniffed out the disease in stool with 97% sensitivity and 99% specificity, Hideto Sonoda, MD, of Fukuoka Dental College Hospital in Fukuoka, Japan, and colleagues reported in Gut.
Dog olfactory detection tests have already been assessed in melanoma as well as bladder, lung, breast, and ovarian cancer. At the same time, several volatile organic compounds have been identified as candidate substances for early detection of cancer using gas chromatography/mass spectroscopy in the exhaled breath of patients with lung and breast cancer.
“We’re always looking for effective and inexpensive screening devices,” Johnson told MedPage Today and ABC News. “Training dogs is not inexpensive, but the cost to the end user is going to be a lot less than many of the tests we have. It wouldn’t be diagnostic though, it would be a screening test used in combination with other tools.”
