Researcher reported that a simple breath test can sometimes detect lung cancer in patients even in the early stages of the disease. The test is possible in principle if someone developed amore accurate version because this breath test device, the size of a coin, had many false positives.
Researchers know that tumor cells produce different compounds than normal cells.
