Laser therapy uses focused light for all kinds of treatment. The light is of a specific wavelength which allows it to focus into powerful beams. The modern technique of treatment needs experts to work with precision. The light should target only the specific area causing minimal damage to surrounding cells and tissues. The use of laser lights varies depending on the purpose of its use. Experts direct the laser light to the specific area after visualizing it through an endoscope and monitor. Endoscope insertion needs minor incisions in the body, or
many times, it may enter through the mouth.
