Laser light is then precisely aimed to cut or destroy a tumor. Laser-induced Interstitial Thermotherapy (LITT), or interstitial laser photocoagulation, also uses lasers to treat some cancers.

In Laser Surgery, an endoscope with a high-intensity laser on the tip is inserted down the throat. The tumor can then be vaporized or cut out using the laser.
