Will there ever be a breath test for lung cancer detection?

Jay M. Lee (Surgical Director, Thoracic Oncology Program, UCLA) gives expert video advice on: How is lung cancer diagnosed?; What are some common non-surgical procedures used to diagnose lung cancer?; Can waiting for a lung cancer diagnosis cause a dangerous delay in treatment? and more...

There's a great deal of research currently going on trying to detect lung cancer, not only with a breath test, but looking at sputum samples, or looking in the peripheral blood. Currently all of these things remain investigational and there are some promising, potentially useful things in the future. But right now we are far from taking this as a standard of care to make a diagnosis of lung cancer.
