The dog saved the owner by smelling cancer before she knew she had it.

The dog has a long history as the best friend of man.

But the story of a police officer in Newburyport and her blind dog from Massachusetts not only proves the relationship between the owner and the pet, but also proves that dogs are very capable of detecting the disease.Police officer Megan Tierney was reportedly at home with a dog Dude , her blind dog of the Australian shepherd's breed, when he began to behave a bit strange.

According to her, she was lying in bed when Dude suddenly became focused on her chest area, putting her paw.

Tierney paid attention to the place where Duda's dog touched her and noticed the swelling of the tissue. But to his surprise, a visit to the doctor confirmed that he had a double negative invasive phase of ductal breast cancer.

And although she found out she had a cancer that was never easy to swallow, she said: "The dude found swelling, and we were never so happy because he discovered it a lot before I could discover it."

It is known that dogs have a much stronger sense of smell than humans. A dude, a blind dog, greatly enhanced that feeling that helped him discover the illness of his owner. Moreover, dogs have 220 million fragrance receptors; 195 million more than people. According to a research psychologist for dogs Alexandri Horowitz of Barnard College, dogs can smell fragrances in ppt (parts per billion). For example, in a million gallons of water, dogs can detect if a teaspoon of sugar is mixed in water. This means that their fragrant abilities are 100,000 times better than ours.

One study, carried out by the Pine Street Foundation Foundation, explains Dude's extraordinary skill. The study included five dogs who received 31 patient samples of breast cancer, 55 patients with lung cancer and 83 healthy people. All dogs could determine which patterns came from those who were ill with about 90 percent accuracy.

Can dogs really smell cancer?

According to Tamany Khare, behind the magazine "Dogs Naturally Magazine, due to the metabolic waste released by cancerous cells, a pronounced scent is released from the human body. This particular scent can easily smell dogs even in earlier stages of cancer. Other studies show that dogs also have the ability to smear skin melanoma traces of skin cancer through skin lesions and to detect prostate cancer only with the urine sample from the person.

"Not only does their sense of smell enable cancer detection, but research suggests that dogs can be actively trained to smack cancer," a dog expert said. "In Berlin, a group of researchers trained some dogs to detect the presence of various types of cancer, including ovarian cancer, bowel cancer, and bladder cancer, skin cancer, lung cancer, and prostate cancer, "Khane concluded.
