Objective: The purpose of this research was to study the Maximal Respiratory Pressures (MRP) after exposure to breast radiation therapy in women. Methods: Prospective observational study performed at the Hospital de cancer Alfred in Campo Grande/MS. The sample of this study consisted of women (N = 16) divided into two groups: women exposed to breast radiotherapy after underwent quadrantectomy surgery (n = 8); and women with no history of cancer (n = 8). We evaluated the strength of respiratory muscles through the Maximal Inspiratory Pressure (MIP) and Maximal Expiratory Pressure (MEP) using the handset called manovacuometer. The examination was performed before the first session and after the twenty-fifth session related to the last day of the radiation treatment; evaluation of anthropometric data of weight and height to detect the body mass index (BMI); evaluation of clinical respiratory symptoms of dyspnea using the Medical Research Council (MRC) Dyspnea Scale and characterization of cough with Common Pulmonary Toxicity Criteria, in the classification of clinical pneumonitis.
