Laser therapies are medical treatments that use focused light. Unlike most light sources, light from a laser (which stands for light amplification by stimulated emission of radiation) is tuned to specific wavelengths.
Lasers are more precise and it causes less damage to tissue.
Laser therapies are usually shorter than traditional surgeries. They can often be done on an outpatient basis. You also don’t have to spend the night in the hospital.
People also tend to heal faster with laser therapies. You may have less pain, swelling, and scarring.
If a tumor is being treated, an endoscope (a thin, lighted, flexible tube) may be used to direct the laser and view tissues inside the body. The endoscope is inserted through an opening in the body, such as the mouth. Then, the surgeon aims the laser and shrinks or destroys the tumor.
