Can Lung Cancer sniffing dogs

According to German researchers, can be used sniffer dogs to detect lung cancer. They have written about it in the European Respiratory Journal, as quoted by the BBC on Thursday (08/18/2011). Their findings show that trained dogs can detect tumors in 71 percent of patients.

However, scientists did not know what chemical elements detected the dogs and that's what they say need to know to develop a screening program. Accuracy and utilization of the findings in the medical life is still very much to say.

The dog was first thought to be "sniffing" of cancer in 1989 and further studies have shown that dogs can detect some cancers, such as skin cancer, bladder, colon, and breast. Tumors are thought to produce "volatile chemicals" that can detect a dog.


The BBC reported, the researchers trained four dogs, two German shepherd dogs, Australian shepherd and a Labrador again, to detect lung cancer. Three groups of patients were tested with 110 healthy people, 60 people with lung cancer, and 50 in the diseased lung with chronic complications, a narrowing of the airways in the lungs.

They all exhale into a tube containing fur, which absorb any odors. The dogs sniffed vials and sat in front of the tubes where the animal was detecting the smell of lung cancer. They succeeded in detecting 71 percent of patients.

The author reports from Schillerhoehe Hospital, Dr Thorsten Walles, said, "In the breath of patients with lung cancer, there is the possibility of different chemicals with an example of a normal breath. Smell sharp dogs that can detect the difference is in the early stages of disease. Our results confirm the presence of markers of lung cancer. It's a big step forward. "

Dogs may not be part of the physician work practices daily, so the researchers are now working on "electronic nose" that will be able to detect chemicals is the same as that dog. These chemicals or combinations of odors has not been found. "Unfortunately, dogs can not communicate aroma biochemistry of cancer," complained the researchers said.

Science information officer at Cancer Research UK, Dr. Laura McCallum, said, "Even now there are some interesting research that shows that the dog smelled cancer may in some situations, we are still far from a proper understanding of the 'odor molecules' where the dog- detection dog and whether the study accurately. The reason, it would be very difficult to use dogs in the clinic. Further studies are being conducted to learn more about the molecules that are released as the tumor and whether the devices 'electronic nose' could sniff molecules help It. "
