      Breath test may detect signs of lung cancer: Study

      Examining breath samples from patients with suspicious growths might help determine who needs surgery.

      (HealthDay News) — A simple breath test might reveal if a person has early-stage lung cancer, according to a new study.

      Researchers tested the exhaled breath of people with suspicious lung lesions that were detected on CT scans. The breath was tested for levels of four cancer-specific substances, called "carbonyls."

      The breath samples were analyzed using a special device developed at the University of Louisville.

      Having elevated levels of three of the four carbonyls was predictive of lung cancer in 95 percent of patients, while having normal levels of these substances was predictive of a noncancerous growth in 80 percent of patients, the researchers found.

      Elevated carbonyl levels returned to normal after lung cancer patients had surgery to remove the cancer, according to the study, which was to be presented Tuesday at the Society of Thoracic Surgeons annual meeting in Orlando, Fla.

      I am posting this article because melanoma can metastisize to the lungs.

                Does it detect just slung cancer or will it detect melanoma cancer in the lungs?  Two different things.

                    This study is from the new field of "metabolomics" ("metabolism" + "the study of"). It appears that different tissues and different cancers metabolize compounds somewhat differently and researchers are only now beginning to devlop sensitive techniques to detect these small differences.

                    Based on this article, this technique will onlyl detect lung cancer in the lungs. But I'm sure the researchers are working to identify metabolites unique to melanoma and other cancers that go to the lungs. Eventually, they hope to be able to detect any type of cancer present in the lungs using just a simple breath test.  Amazing, isn't it?

                          Afraid that would be the answer.  Many small steps.  Would love to see some BIG ones!
