To explore the symptoms of nutritional impact, a checklist of 12 items was used, with 8 items on symptoms affecting the function and / or integrity of the digestive tract and other 4 characteristics that may be associated with decreased oral intake. Descriptive statistics were performed. For the description of the studied variables, the mean and standard deviation measures were used for continuous variables, and percentages for categorical variables were used.Results:. The majority of the participants were female (63.3%), married (69.4%), without work activity (53.1%) and belonging to economy class B (59.2%). Prevalence of breast cancer (30.8%), stage III (37.2%) and non-metastatic (61.2%) was predominant in this sample. Three items of the instrument presented an incomprehension index - II> 20%, which were reformulated in order to facilitate the interpretation of the interviewees, since item 12 (other reasons), although the participants understood, received explanations in order to exemplify the "other motives ". Regarding the nutritional impact symptoms observed in this population, the most prevalent were "taste and smell changes" and "fatigue", which regardless of the intensity, were reported by a large proportion of participants in this study with prevalences of 46.9% and 42.5%, respectively.
