Human breath may help doctors test for lung cancer

December 28, 2011

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. They found that the tests 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. It could be used in helping doctors distinguish between benign and malignant lung tumors.
