Intravenous laser<unk><unk>  Intravenous<unk><unk> . Intravenous or intravascular laser<unk><unk>  (ILBI) involves the in-vivo illumination of the<unk>  by feeding low level laser light generated by a 1–3 mW helium–neon laser at a wavelength of 632.8 nanometers (nm) into a vascular channel, usually a vein in the forearm, under the assumption that any therapeutic effect will be circulated through the circulatory system. Most often wavelengths of 365, 405, 525 and 635 nm and power of 2.3 mW are used. The technique is widely used at present in Russia, less in Asia, and not extensively in other parts of the world. It is shown that ILBI improves<unk>  flow and its transport activities, therefore, tissue tropism, has a positive effect on the immune system and cell metabolism. This issue is subject to skepticism. Transcutaneous laser<unk><unk>  Transcutaneous therapy applies laser light on unbroken skin in areas with large numbers of<unk>  vessels (such as the forearm). Because of the skin acting as a barrier to the<unk> , absorbing low level laser energy, the power of the laser is often boosted to compensate. The problem can be solved by using pulsed matrix laser light sources. Extracorporeal<unk>  Extracorporeal<unk>  is used only for ultraviolet<unk><unk> , that involves drawing<unk>  out through a vein and<unk> g it outside of the body. Though promoted as a treatment for cancer, a 1952 review in the Journal of the American Medical Association and another review by the American Cancer Society in 1970 concluded the treatment was ineffective.
