Therapeutic lasers work on the cellular level, enhancing the fundamental functions of the cells. This means that any pathological condition theoretically can be improved, if the suitable

The ideal tool for preventing radiodermatitis is an agent that mediates DNA repair or promotes cell proliferation. Application of a low-power laser has been shown to promote tissue repair by reducing inflammation and inducing collagen synthesis. Moreover, this treatment approach has not been associated with adverse events and is cost-effective.
