It is considered that patients undergoing radiotherapy in use gel based on C. recutita or use of cream based urea three times a day, concomitant radiotherapy, would present the following hypotheses:
* Null: equal incidence and severity of radiodermatitis when compared to the control group (usual care);
* Alternative 1: low incidence and severity of radiodermatitis when compared to patients who comprised the control group (usual care).
* Alternative 2: lower incidence and severity of radiodermatitis between the experimental groups (urea and chamomile).
