The most articles I have read concerning the use of LED' s and cancer refer to how the light is used to activate a chemical that has been injected. This chemical is absorbed more by cancerous cells than healthy cells. After absorption, the area is exposed to the light and the chemical is made active by this light. Once it becomes active, it kills the cancer cells and does very little damage to healthy ones. But it is not the light that gets the cancer; it is the chemical. Porphyrins of some kind if I recall correctly. Most sites that sell LED'S caution against using them on cancer or on pregnant women. I have emailed a couple of these sites and they don't seem to be able or else don't want to, offer any info as to why they should not be used on cancer. I have read that the red led's cause blood vessels to grow faster so that would nix using it on cancer as they have more vascularity than regular cells---maybe. Also, since cancer cells grow more profusely, you wouldn't want to increase their energy--might make a bad situation worse. The www.educate-yourself.com site mentions using green led's for cancer (Dinshah, I guess) so I will try to get more info from them. When I learn anything, I will sure post it. The reasons I have given as to why the led's aren't recommended for cancer is just what I surmise. I sure would like to hear about any tryouts on any animals, but so far I have not found any. I have found that a few herbs cause photosensitivity, but I don't know if that could be used by regular people to treat a cancer or not. Doesn't seem likely, but I will sure play around with them when and if the time comes. Meantime, V's unit continues to give my husband a much better quality of life. Thank, V!! pj
