Three types of lasers are used to treat cancer: carbon dioxide (CO 2) lasers, argon lasers, and neodymium:yttrium-aluminum-garnet (Nd:YAG) lasers. [1] Laser therapy is often given through a flexible endoscope (a thin, lighted tube used to look at tissues inside the body).
Low-level laser therapy (LLLT), cold laser therapy, photobiomodulation (PBM) or red light therapy is a form of medicine that applies low-level (low-power) lasers or light-emitting diodes (LEDs) to the surface of the body.
Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. The practice was originally developed in the United States, [1] but most recent research on it has been conducted in Germany (by UV lamps ) and in Russia (in all variants).
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery .
Photodynamic therapy ( PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death ( phototoxicity ). [1] PDT is used in treating acne, wet age-related macular degeneration, psoriasis, and herpes.
Photothermal therapy (PTT) refers to efforts to use electromagnetic radiation (most often in infrared wavelengths) for the treatment of various medical conditions, including cancer. This approach is an extension of photodynamic therapy, in which a photosensitizer is excited with specific band light.
