Introduction: For Brazil, the INCA estimate is 66,280 new cases of breast cancer for each year of the 2020-2022 triennium. The treatment of breast cancer depends on the stage of the disease and the type of tumor. Treatment modalities are divided into systemic (chemotherapy, hormone therapy and biological therapy) and local (radiotherapy and surgery) that can be performed alone or in combination, according to clinical and tumor characteristics. Radiotherapy is associated with some adverse effects, including radiodermatitis, which is characterized by tissue damage that occurs immediately after the first radiotherapy session and, as subsequent sessions occur, resulting from dose fractionation, it starts to the dose accumulates in the skin, which causes the recruitment of inflammatory cells and the worsening of this complication. General objective: To evaluate the effectiveness of photobiomodulation with the application of the LED board in the prevention of radiodermatitis in women with breast cancer undergoing adjuvant radiotherapy at the Cancer Hospital III of the National Cancer Institute (HCIII/INCA). Materials and methods: This is a Randomized Controlled Clinical Trial Women with breast cancer who are indicated for treatment with adjuvant radiotherapy will be eligible. Patients who underwent surgery and/or chemotherapy outside the institution and patients with comprehension difficulties will be excluded. After recruitment, women will be allocated into two groups: intervention (use of LED board) and control (placebo board). The degree of radiodermatitis, pain, edema and/or lymphedema, paresthesia, functionality, quality of life, skin conditions and related independent variables, such as the characteristics of the patient, the tumor and the oncological treatment performed will be evaluated.

Thus, the hypothesis of the study is the prevention of radiodermatitis, which is a complication of radiotherapy treatment using photobiomodulation with LED board as a means of intervention.
