The image on the left is a piece of lung tissue that contains a tumor viewed under normal white light. The right image shows the same piece of tissue after Tumor Paint has been applied. Here it's viewed under infrared light. Areas that are more red and yellow show a concentration of the paint, which means they are more likely to be cancerous.
