A smoker's risk for lung cancer may soon be predicted through a simple urine test.
University of Minnesota researchers say smokers who develop the disease produce higher levels of two tobacco-related compounds.
Those with the two compounds are nine times more likely to develop lung cancer.
Since the compounds can be detected in the urine, the hope is for scientists to develop a simple urine test to spot those at the highest risk.
However, the research is still in its preliminary stages... And we may be several years away before it could become available.
