Detecting Cancer via a Patient’s Breath and Lasers

Here’s another paradigm-shifting innovation in diagnostic medicine! Researchers at the University of Colorado are using a patient’s breath and lasers to detect cancer and asthma (and possibly additional diseases in the future). The technology measures a patient’s breath by using mirrors to bounce a laser’s light back and forth until it has touched every molecule a patient exhales in a single breath.
