Doctors have taught the dogs "sniff out" lung cancer

Sniffer-dogs can be used for early detection of lung cancer. This is the conclusion of the hospital doctors in Germany Schiller

A study conducted by hospital staff, was the first work that has demonstrated that the legged really able to sniff out endungeoned, reports compulenta.ru.

As you know, lung cancer - the second most common type of cancer in Europeans, annually die from the disease of more than 340 thousand people. In addition, the most common cause of death Cancer around the world.

Insidious disease that takes almost no symptoms and early diagnosis of her often purely accidental. Existing diagnostic methods are unreliable, so scientists working on new ways to detect, provide analysis of exhaled air in patients volatile organic compounds (VOCs) associated with cancer. However, while the use of these tests in clinical conditions associated with a number of difficulties: checked do not eat or smoke before the procedure, an analysis of the sample takes a lot of time at high risk of interference. That's why so far not been identified VOCs characteristic of lung cancer.

In this study, the researchers tried to find out whether you can use sniffer-dogs to detect VOCs in exhaled air. We took part in 220 volunteers, including patients with this endungeoned with chronic obstructive pulmonary disease (COPD) and healthy subjects. Participating in the experiments the dogs were to coach a particular way. To determine whether the dog to distinguish between a cancer patient from a healthy person or suffering from chronic obstructive pulmonary disease, and determine whether such an analysis be effective in the presence of tobacco, the researchers have conducted many tests.

Bloodhounds have successfully identified 71 air samples of cancer patients out of 100 possible and correctly identified 372 out of 400 samples belonging not suffering from cancer. In addition, recognize lung cancer, regardless of COPD and tobacco smoke.

The results confirm the presence in the breath of cancer patient’s markers of lung cancer that is not dependent on the presence of COPD in humans and are distinguishable even when such interference, as cigarette smoke, the smell of food and medicine.
