Final answer:
Laser technology is more effective than conventional surgery as it minimizes damage to surrounding tissues, increases precision, and reduces the risk of bleeding and infection.
Step-by-step explanation:
Laser technology is more effective than conventional surgery in removing cancerous tumors because it minimizes damage to surrounding tissues. Unlike traditional surgery methods, laser devices deliver a high-intensity beam to the target area, which can be very precisely focused and is preferentially absorbed due to its single wavelength. This allows for more accurate cutting or burning away of tissue, resulting in less bleeding and, subsequently, a lower risk of infection. Notably, in procedures like repairing detached retinas with a green argon laser, laser surgery takes advantage of the laser's capacity to coagulate or "weld" tissue by being strongly absorbed by tissues containing blood. Furthermore, in dentistry, lasers help to remove ulcers, stop bleeding, and reshape gum tissue with increased precision and reduced healing time.
