Can LLLT cause cancer?
The answer is no. No mutational effects have been observed resulting from light with wavelengths in the red or infrared range and of doses used within LLLT. But what happens if I treat someone who has cancer and is unaware of it? Can the cancer’s growth be stimulated? The effects of LLLT on cancer cells in vitro have been studied, and it was observed that they could be stimulated by laser light. However, with respect to a cancer in vivo, the situation is rather different. Experiments on rats have shown that small tumors treated with LLLT can recede and completely disappear, although laser treatment had no effect on tumors over a certain size. It is probably the local immune system, which is stimulated more than the tumor. The situation is the same for bacteria and virus in culture.

These are stimulated in vitro by laser light in certain doses, while a bacterial or viral infection is cured much quicker after the treatment with LLLT. What happens if I use a too high dose ?
