This study will attempt to replicate the findings of Dr. DeLand's study by randomly assigning at least 40 breast cancer patients to either a treatment group or to a control group. The treatment group will receive LED photomodulation treatments before and after each radiation treatment with the Gentlewaves Select™ handheld high energy 590nm LED array using specific sequences of pulses used in other studies; the treatment group will also receive 7 additional treatments over 2 weeks after their radiation treatment course is completed. The control group will receive no LED treatment but will use the exact same skin care regimen as the treatment group. In addition to weekly evaluation and grading of skin reactions, subjects will be photographed under standardized conditions weekly and then photographs will be evaluated and graded by blinded dermatologists.
