Can dogs detect cancer?
Dogs are creatures with an extraordinary sensitivity, especially if we talk about their olfactory ability. It has been proven that dogs have 25 times more olfactory receptors than humans , so their ability to smell less noticeable odors is much higher.
CAT Spraying No More REVIEW
Cat Spraying No More is an excellent opportunity for the cat owners to learn about training the cat with a systematic approach. It helps in preventing the unwanted litter issues and other risks of bad feline behavior as well.
However, the idea of a dog smelling the presence of diseases or anomalies present in the body, such as cancer, could be impressive. For this reason, animalistic scientists have given themselves the task of investigating whether this is a real possibility.
If not at once already wondered if, dogs can detect cancer? Continue reading this article from YourCatCareguide and find out if it is a myth or it is true.
The canine abilities
Studies state that a dog’s brain is virtually completely controlled by the olfactory cortex, unlike people, where it is controlled by visual ability or visual cortex. This canine olfactory cortex is 40 times larger than that of a human. In addition, the olfactory bulb in a dog has hundreds of millions of receptors sensitive and reactive, built to perceive odors at long distances and aromas extremely imperceptible to the human nose. So it would not be surprising if dogs had the ability to smell much more than we even imagined.
All these evolutionary and genetic abilities in dogs are almost considered extrasensory abilities , because not only do we speak of the sense of smell, a more physical theme, but also the ability to feel and glimpse things that humans are not capable of. This wonderful sensitivity is called “unprecedented perception.” Dogs may also come to realize the pain and depression of others.
A number of studies and experiments have been conducted over the years, such as a study published in the British Medical Journal, which states that dogs, especially those trained to develop these “gifts” have the ability to to detect diseases in initial states such as cancer, and that its effectiveness reaches 95%. That is, dogs can detect cancer.
Although all dogs possess these abilities (because they are found naturally in their physical and emotional DNA) there are certain breeds that, when trained for these purposes, have better results in the detection of cancer. Dogs like the Labrador, German Shepherd, Beagle, Belgian Malinois Shepherd, Golden Retriever or Australian Shepherd, among others.
How does it work?
Dogs detect for themselves the presence of some malignant active in a person’s body. If the person has a localized tumor through the nose, they can locate where the anomaly is, try to lick it and even bite to remove it. Yes, dogs can detect cancer, especially those who are trained for it.
In addition, through the smell of breath tests and feces, the dog is able to detect the presence of negative traces. Part of the “almost miraculous” training of dogs is that when they realize that something is wrong after the test, the dog immediately sits down, which is a warning.
Dogs, our canine heroes
Cancer cells release toxic waste very different from healthy cells. The difference between the smell between them is obvious to the developed canine smell. The results of the scientific analysis say that there are chemical factors and elements that are unique to a certain type of cancer, and that these go through the human body to such a degree that a dog can detect them.
It’s wonderful what dogs can get to do. Some experts have come to the conclusion that dogs can smell the presence of cancer in the intestines, bladder, lung, breast, ovaries, and even skin. Their help is incalculable because with the proper and early detection we can prevent these localized cancers from spreading throughout the body.
