Study: Laser-guided technique can improve brain tumor removal

Laser-guided surgery could improve the odds of removing all of a brain tumor by highlighting its edges, a new study published in the journal Science Translational Medicine has found. As BBC News reported, removing a brain tumor is "a balancing act--take too little and the cancer could return, take too much and it seriously affects a patient's quality of life."

The researchers, from the University of Michigan Medical School and Harvard University, developed a new method for analyzing tissue--called SRS microscopy--while it is still in the brain, according to the BBC article. A laser is fired at the tissue, and the properties of the beam of light change depending on what it hits. Article
