Three types of lasers are used to treat cancer:
carbon dioxide (CO2) lasers
argon lasers
neodymium:yttrium-aluminum-garnet (Nd:YAG) lasers
CO2 and argon lasers can cut the skin’s surface without going into deeper layers. So, they can be used to remove cancers on the surface of the body, such as skin cancer.
The Nd:YAG laser is more often used through an endoscope to treat internal organs, such as the uterus, esophagus, and colon.
Nd:YAG laser light can also travel through optical fibers into specific areas of the body during LITT.
Argon lasers are often used in photodynamic therapy.
