Electronic nose 'names' malignant tumors

Researchers have designed an electronic nose to help diagnose malignant mesothelioma very early, just by a breath test, according to Top News.

Malignant mesothelioma is the tumor of the lung mucosa and chest cavity or mucosa of the abdomen (peritoneum) that occurs due to long-term exposure to asbestos. This is a rare and often fatal form of cancer.

This non-invasive testing device is the research result of a group of experts from the University of New South Wales (Australia). The device is designed to distinguish between benign and malignant diseases and early detection.

"If you discover the disease earlier, the chances of getting the right treatment to prevent the disease spread will be much greater ," said the team leader, Associate Professor Deborah Yates.

Asbestos-related diseases affect thousands of people, killing about 20,000 people worldwide each year. Malignant mesothelioma is a rare tumor that is often difficult to diagnose in the early stages of the disease.

The researchers said that the usual techniques for distinguishing between malignant and malignant asbestos-related diseases are currently inaccurate and invasive and difficult to implement in most elderly people with this disease.

Ms. Yates and her colleagues analyzed breath samples of 20 patients with malignant mesothelioma, along with 18 people with asbestos-related diseases and 42 healthy people. The patient was correctly identified in 88% of cases.

The technique, which looks at the characteristics of exhaled breath, called an electronic nasal membrane of carbon polymer, can accurately differentiate between patient groups, and can therefore become a effective screening tool. fruits for high-risk people.

Research results have been published in the latest European Respiratory Journal issue.
