LOUISVILLE, Ky. (WDRB) -- University of Louisville medical researchers have developed a breath test that may diagnose early stages of lung cancer, according to a university news release.
Dr. Michael Bousamra, associate professor of Cardiovascular and Thoracic Surgery at U of L, and other researchers confirmed the discovery by testing patients with suspicious lung lesions.
Using U of L-developed technology to test exhaled breath, the researchers found that elevated levels of compounds known as carbonyls were 95 percent predictive of lung cancer.
"Instead of sending patients for invasive biopsy procedures when a suspicious lung mass is identified, our study suggests that exhaled breath could identify which patients may be directed for an immediate intraoperative biopsy and resection," Dr. Bousamra said.
U of L released the study Jan. 28 at the 50th Annual Meeting of The Society of Thoracic Surgeons.
