Radiation dermatitis is a common side-effect of radiation therapy in cancer patients who frequently can experience redness, pain, crusting, and even ulceration of the skin causing suffering and treatment interruption. A recent retrospective study by DeLand demonstrated that administering light emitting diode (LED) photomodulation after each radiation treatment for breast cancer decreased radiation dermatitis in a majority of patients. LED photomodulation is a process by which specific sequences of light are used to regulate or manipulate cell activity without causing heat or damage to the skin. Each LED treatment is painless and is completed in usually less than one minute. LED photomodulation may reduce the suffering associated with radiation treatments, improve cosmetic outcome in radiation fields, and eliminate breaks in radiation treatments which may be required because of severe ulcerating reactions.
