Laser surgery uses a focused, high-powered beam of light to destroy cancer cells. It's often used to control tumors that are causing certain symptoms because of their size or location. Lasers may also be used to activate a cancer-killing chemotherapy agent.

Laser surgery can be very precise and as a result, patients often have less bleeding and scarring and recover sooner. However, the results of the surgery may not last as long, often making repeat procedures necessary.
