Detection of lung cancer through ... breath

There is a method to detect signs of lung cancer, which is simple but effective, which is a breath test. After an experimental process, US researchers on 25.2 announced this in " Thorax " and confirmed that just breathing in the test machine could detect lung cancer at an early stage.

After 12 minutes of breathing test, 3/4 of the participants were diagnosed with lung cancer. However, there are still many cases of false detection and need more testing.

The compact portable breath testing machine has 36 small dots. These compounds will change color if they react to the cancer compound when the patient exhales. This principle of operation is based on a principle that tumor cells produce compounds other than normal cells. In lung cancer patients, these volatile organic compounds are more easily detected.

So far, the most accurate " machine " to detect cancer is . dogs. Last year, researchers found dogs could smell "cancer" through patients' breaths with 99% accuracy.

Early detection of lung cancer, while still capable of treatment, can protect tens of thousands of lives in the United States each year. Lung cancer is the most common form of lethal cancer, killing most people in part because it is often not detected early.

Last year, more than 174,000 Americans were diagnosed with lung cancer, of which more than 160,000 were killed. Lung cancer also kills 1.3 million people worldwide every year.
