Dogs can detect cancer
Yes, dogs can smell cancer. They can even smell in step zero. The study found that dogs can detect prostate cancer with 98 percent certainty. Scientists' Medical Detection Dogs ", located in the UK have discovered that dogs can detect bladder cancer and prostate cancer. This cancer is more common in the UK, with 40,000 cases diagnosed each year.
the new Italian study by the Department of Urology at "Humanitas Clinic and Research Center" in Milan confirmed these claims. with the help of two German shepherds they were capable of detecting prostate cancer with 97.7 percent accuracy.
is exciting to have a detection system high performance such cancer, for which previous tests were inadequate. currently, doctors use a combination of blood tests, physical examination and biopsy to diagnose this disease. But it seems that this is a waste of resources when there are dogs that can detect cancer safely.
Let's take a look closer at why dogs are still interested in smell cancer in the first place. Why you are interested in a dog smell cancer? There must be something in it for them. The key here is that the dog uses nose for our benefit.
Top evolutionary biologists and dog and wolf are now saying that man can never have done beyond the agricultural stage without the dog (and nose). So why would a dog wanting to smell cancer? The answer is simple: if something is wrong with us, this will affect the dog. If we are sick, this could directly affect our ability to provide food and shelter for the dog.
Dogs can smell in parts per billion. An example of this is: one cc of blood diluted in 20 Olympic-sized pools. The dog can smell easily there blood in the pool. We have trained dogs to smell gunpowder, narcotics, missing persons, and now, finally, illness.
The interesting part of this is that the cancer has not quite an odor. Most oncologists will tell you that humans can actually smell the advanced cancer through breathing patients. If we can smell it on stage 3-4, and of course a dog would be able to detect the odor much earlier, in stage 0, 1 or 2. So far, the only people who can smell cancer in early stages, are the dogs.
train dogs to sniff cancer is carried out in the same way as with bombs and narcotics dogs are trained to match the particular smell with a prize of high value. With encouragement, however, things can be a bit tricky. Remember, drugs and gunpowder can be isolated, but "the smell of cancer" is one of thousands of organic compounds within a breathing human beings. For dogs to generalize the "smell cancer" many samples should be used with the common odor. They also have to be trained to ignore healthy breathing and other breathing with diseases other than cancer.
This means a lot of samples are used for training dogs. cancer samples, disease controls and healthy controls are needed, and order and the details of the introduction of cancer through training later stage is extremely specific, so the dog to generalize the smell of cancer . At this time, it is important to remember that dogs can smell cancer.
