One reason cancer is so difficult to treat is that it avoids detection by the body.

Now, researchers at the University of Pennsylvania School of Engineering and Applied Science and Penn's Perelman School of Medicine and Physical Sciences Oncology Center have learned how to re-engineer macrophages, the "first responders" of the immune system, so that they can distinguish between healthy and cancerous cells.
