Guest dogs (certain introduction)
As early as the late 1980s, there was Scientists have proposed that dogs can detect malignant tumors through their breath, so dogs have another task - to help doctors determine the number of cancer patients. But many people have doubts about this-how dogs can smell the smell of cancer patients.
We all know that dogs have very sharp senses, but many people may have no idea how sharp they are. Simply put, dogs can distinguish 200 different odors with different concentrations, which is almost impossible for humans. In addition, dogs can sense smells at the molecular level. For example, if you add a small spoonful of salt to 500kg of water, your dog can smell it by just moving its nose. Can you?
Scientists say that the smell carried by cancer patients is different from that of healthy people, because tumors produce some evaporative substances. Although humans cannot smell this smell, dogs can smell it. They are absolutely capable, and the trained dogs’ judgment accuracy is extremely high. The latest research report shows that dogs can determine the number of bladder cancer by smelling urine, lung cancer by smelling the breath of celebrities, colorectal cancer by smelling feces, etc., and their accuracy is as high as 90%.
If dogs can really join the hospital and become "dog doctors", then this will bring great convenience to doctors and patients. For example, if you want to determine whether suspected patients have colorectal cancer, then these suspected patients need to undergo multiple colonoscopy examinations. However, colonoscopy examinations will cause severe discomfort in people, but allowing dogs to detect them by smelling their breath The diagnosis and treatment will not cause any pain to the viewer, and the examination will become easier.
However, many people still say that if they need to go to the hospital for cancer screening one day, they will definitely choose the data measured by the trustworthy instrument instead of letting the dog smell it. Make a judgment.
