has tumors, it will destroy the physiological structure of the human body, which will lead to changes in the overall metabolic mechanism and also changes in VOCs. As a result, trained dogs can detect changes in the odor of these VOCs through their keen sense of smell, and can make more rapid alerts than medical tests. How are medical detection dogs trained? Before training a medical detection dog, the most important thing is to understand whether the disease will affect the health of the dog, to ensure that the health of the dog is the first priority. Take lung cancer detection dog training by sniffing exhaled gas as an example. Scientists or doctors will first collect the breathing gas of lung cancer patients and provide them to dogs for training (target training).
Sit down as the response mode, and then add breath samples provided by healthy people to the dog to sniff (non-target training). At this time, the dog only needs to learn to respond to the target and ignore the non-target. Most importantly, when sms services doing disease detection training, dogs need to be trained with a variety of individual target or non-target samples to ensure that they are detecting the smell of the disease, not the patient. smell. image1 Photo Credit: Courtesy of Chen Xiaozhu To train medical detection dogs, researchers first collect the gas a patient breathes. image3 Photo Credit:

Detection dogs that use smell to help diagnose diseases At present, a large number of studies have proved that dogs can detect diseases by smell, including cancer, neurological diseases, malaria, bacterial infections, etc., and can even detect COVID-19 (serious special infectious pneumonia, new coronary pneumonia). , Wuhan pneumonia). Here are some examples of common diseases that can be detected by dogs: cancer In recent years, cancer has ranked first among the top ten causes of death in Taiwan, but most cancers have no early signs. When diagnosed, they are usually at an advanced stage.
