What an incredible medical discovery we have made together! A contagious cancer is one of the rarest diseases throughout the galaxy. If left untreated, the cancer will not only spread from the lungs to other organs, but will spread from sick gliders to healthy gliders. Fortunately, we have collected data needed to determine how the tumor cells differ from healthy cells. The elevated concentration of Growth Factor L in the blood of spotted gliders provides a clue to the mutations responsible...
