Dog will catch cancer also


In Melbourne Australia Japanese scientists claim that a Labrador dog can detect bowel cancer from sniffing breath and stool samples very accurate. The research contacted by Hideto Sonoda at Kyushu University in Fukuoka, Japan, they says that the findings support hopes for an ‘electronic nose’ that could one day sniff a tumour at its earliest stages, helps in treatment. In this study they used a specially trained female black Labrador dog to carry out 74 sniff tests, for several months, each of the tests comprised five breath or stool samples, only one of which was cancerous. The samples came from 48 people with confirmed bowel cancer at various stages of the disease and around 258 volunteers with no bowel cancer or who had had cancer in the past. They include samples from smokers and other types of gut problems, which might have masked or interfered with other smells, but these did not interfere with the dog’s olfactory accuracy.
Around half of the non-cancer samples came from people with bowel polyps, which are benign but are also a possible precursor of bowel cancer. Six per cent of the breath samples, and 10 per cent of the stool samples, came from people with other gut problems, such as inflammatory bowel disease, ulcers, diverticulitis, and appendicitis. In study retriever performed as well as a colonoscopy, a technique in which a fibre-optic tube with a camera on the end is inserted into the rectum to look for suspect areas of the intestine.

The dog correctly spotted which samples were cancerous and which were not in 33 out of 36 breath tests, equal to 95 per cent accuracy, and in 37 out of 38 stool tests (98 per cent accuracy).
The researchers say that this study shows that cancer cells give off specific discernible odours as they circulate through the body. Some previous studies proved that dogs can sniff out the bladder cancer, lung cancer, Brest cancer etc
