Introduction: Radiotherapy (RT) is a widely utilized treatment in cancer management. However, one of the most frequent adverse effects of this procedure is radiodermatitis (RD), which can result in pain, reduced quality of life, and, in severe cases, discontinuation of RT. Photobiomodulation (PBM) has emerged as a promising therapeutic approach capable of aiding in the management of this oncological condition. Objective: To evaluate the regenerative potential of physiotherapeutic treatment with PBM regarding pain, degree and severity of radiodermatitis, and quality of life in patients with breast cancer. Methods: A quasi-experimental quantitative study involving 9 breast cancer patients with RD following radiotherapy. The PBM protocol employed a cluster device with red LED (658 nm), infrared LED (858 nm), and red laser (660 nm), simultaneously irradiated with an energy density of 4 J/cm². The devices were applied perpendicularly to the affected areas twice a week for 3 weeks, totaling 6 sessions. Pain was assessed using the Numeric Pain Rating Scale (NRS), RD was evaluated using the Radiation Therapy Oncology Group (RTOG) acute morbidity scoring criteria and the Radiation-Induced Skin Reaction Assessment Scale (RISRAS), and dermatological quality of life was measured using the Skindex-16 questionnaire. Results: There was a significant improvement with a reduction in pain (p = 0.018), degree (p = 0.046) and severity of radiodermatitis (p = 0.028), in addition to an increase in dermatological quality of life (p = 0.038). Conclusion: FBM demonstrated to be a promising strategy to treat radiodermatitis, promoting tissue regeneration and symptom relief. However, additional studies with a larger number of participants are necessary to validate the results obtained.
