Lead researcher for the study was Dr. Hideto Sonoda, from the department of surgery at the Postgraduate School of Medicine at Kyushu University in Fukuoka.
According to the article, "For the study, Sonoda’s group collected samples of stool and exhaled breath from 40 patients with colorectal cancer and also from 320 healthy people. ‘The tests were conducted from November to June, because the dog’s concentration tends to decrease during the hot summer season,’ Sonoda noted.
"The dog was able to distinguish cancerous samples from noncancerous samples in 33 of 36 breath tests and in 37 of 38 stool tests, the researchers found. ‘Moreover, canine scent judgment even appeared to be highly accurate for early-stage colorectal cancer,’ Sonoda said."
