Dogs sniff out drugs, currency, and even explosives. Now the media and researchers are happy to know about this new feature of dogs that can diagnose cancer.
For example, in 2016, actress Shannon Doherty claimed that her dog had diagnosed her breast cancer before the doctor. More and more people seem to be claiming that their dog’s behavior had become awkward and that they had begun to claw at the cancerous part of their body when they later found out that they had cancer there.
Similarly, some studies have confirmed that dogs have the ability to detect breast cancer, lung cancer, and prostate cancer. In 2006, US scientists said they had succeeded in detecting lung cancer in dogs in 99 percent of cases. But on the other hand, critics say that no patient’s life can be played with because dogs are not so reliable.
Also in 1989, scientists suggested that dogs have a higher sense of smell and that it could be used to detect cancerous cells. Dogs have the ability to smell unusual organic compounds caused by cancer, and they detect cancer by sniffing human breath, urine, and human skin.
“We don’t know what the special thing is that makes a dog react,” said Peter Boeker, a professor of gas emissions research at the University of Bonn in Germany. Failed to find out what affects dogs’ sense of smell? Scientists believe that these may be different carcinogenic elements, which together produce a specific odor, which only dogs can smell.
The UK’s National Health Service has launched a project in this regard. A study conducted under this study found that in 93% of cases, dogs were able to diagnose cancer.
On the other hand, critics say that recognizing cancer through dogs in hospitals is a very difficult stage. On the one hand, it will take a lot of time and money to train dogs, and on the other hand, it is impossible to provide trained dogs in hospitals all over the world.
