Randy Atkins:  Lung cancer is especially dangerous, because it’s usually found too late.  So Dr. Peter Mazzone, of Cleveland Clinic, is designing a simple breath test using an array of chemically-sensitive dye dots.

Peter Mazzone:  They were seventy to seventy-five percent accurate in distinguishing between lung cancer and no lung cancer simply based on the pattern of color changes.

Randy Atkins:  But Mazzone says it needs to be even better.  So he’s preparing sensitive experiments to ID the unique gases produced by lung cancer cells.

Peter Mazzone:  When we find exactly what chemicals we should be looking for, we would be able to go back to those sensor systems and fine-tune them for the chemicals that are most important.
