It is known that the dog’s sense of smell is superior to and exceeds the sense of smell in humans, but no one knows the extent of the limits of the dog’s nose ability; The dog can be trained to detect explosives and drugs, they can track the smell of a missing person, and they can smell the blood sugar level of diabetics, but the most important question now is can the dog smell cancer? If you want a short answer, yes, a dog can smell cancer, but a longer answer is more interesting. Dogs are exceptional creatures. They guard and guide us and alert us to diseases even before the results of laboratory tests appear.
Another example is a dog that did not stop smelling a mole on its owner’s leg, and it turned out that this mole was not benign, but rather skin cancer.
Dogs have the ability to smell the organic component resulting from cancer in the skin, chest, prostate, and others.
Dogs trained to detect medical diseases can learn to refer to their trainers when they detect any smell of cancer in the samples taken, and some dogs have been trained to differentiate between different types of cancer.
Types of cancer that dogs can detect:
We have learned that the dog can smell cancer in the human body, but the question now is how the dog detects cancer in the human body.
Dogs and humans have coexisted side by side for hundreds and thousands of years; The amazing bond that we share with our dogs today is the result of the emotional attachment that occurred between the first pet dog and its owner; People and dogs need each other to survive.
As a result of the developed sense of smell in dogs, they can smell the smell of weak and sick animals, the animal is easier to eliminate than a healthy animal.
And dogs can now smell disease in humans as a result of the process of their development as predatory animals.
Pets do not need these days to use their sense of smell in order to smell a sick animal, but they use their nose to smell the smell of weakness and disease in humans as a means of self-preservation as their basic instinct warns them, as the presence of any illness in us may affect our ability to provide shelter And food for them.
How does a dog’s nose work:
The dog relies on its sense of smell in order to roam the world, as the aromatic crust in the dog’s nose is 40 times larger than that of humans, as humans do not need such a size because they use vision to roam the world.
While humans have about 5 million receptors for smell, dogs have 300 million. They even have an additional olfactory system called Jacobson, which is considered a second canine present in order to improve the smell process in dogs.
Therefore, a dog can differentiate between trillions of smells, while a human can not differentiate between 3 types of cheese smell.
Gifted breeds: Which dogs are better at smelling?
Dogs can smell 100,000 times better than us, but the fact that some dogs do not have a super sense of smell does not mean that they are in a lower rank, so they can still smell much better than us. But despite that, there are some species that are known to have distinct olfactory skills, including:
Portuguese Water Dogs
Why are there not dogs that detect cancer in every hospital?
Training one dog to detect cancer in a patient’s body requires a lot of time, energy and resources, and a group of small trained dogs are used in studies to detect the presence of cancer and work on a small scale.
Dogs versus machines: How dogs are helping revolutionize disease discovery.
Dogs may not be the future of detecting cancer and other diseases. They are simply helping researchers to create an electronic nose that will be designed to detect the presence of diseases such as cancer and others at a low cost. Dogs help scientists identify the odors of organic waste that result from cancer and once identified by The dog’s nose, so scientists should program the electronic nose on that component.
What makes dogs’ noses so special is that they can detect cancer at the beginning of its formation, and the electronic nose must be able to do the same.
Despite how wonderful science is, devices cannot replace our need for dogs or their noses.
