Researchers at the Cleveland Clinic and the University of Illinois used a special breath analyzer to look for signs of lung cancer in 229 people.
When we exhale we emit a unique pattern of organic compounds that reveal a lot about what is going on inside the body. Studies found that the testing of those compounds were accurate in detecting the cancer better than 80 percent of the time.
Researchers say the goal now is to develop a low cost breath test that would be combined with a CAT scan.
