How can laser beams be used in medical applications?

Laser beams play a versatile role in the medical field, being employed in various procedures that go beyond a singular application. They are utilized in cutting through tissues, which is particularly useful in surgical contexts where precision is crucial. Coagulation is another critical use, allowing for the rapid sealing of blood vessels to minimize bleeding during surgeries. Ablation, the process of removing tissue or destroying dysfunctional tissue, is effectively achieved using lasers, which can target specific areas without affecting surrounding tissues.

This multifunctionality makes lasers invaluable in both surgical and therapeutic procedures, including but not limited to dermatology, ophthalmology, and oncology. In contrast, other options suggest limitations that do not reflect the true breadth of laser applications in medicine—as lasers are not restricted solely to skin resurfacing, diagnostic purposes, or cosmetic enhancements. By recognizing the wide-ranging uses of lasers, this understanding underscores their significant impact and importance in advancing medical practices.
