Abstract
Objective: to review in the scientific literature the nurse's role as pain control in cancer patients and to discuss the challenges and difficulties experienced by these professionals. Methods: This is a bibliographical research in which 12 articles were found using the scientific article database from 2010 to 2015. Results: It is possible to recognize pain through the patient's behavioral and emotional reactions that alter Their physiological factors, such as blood pressure, respiration, and heart rate. Measurement of pain in cancer patients can be performed using the visual analog scale of faces (VAS) and numerical verbal scale (NVA). The nurse can act on pain relief through holistic therapies. One of the great challenges for nursing is to be able to effectively evaluate pain in all aspects of biopsychosocial aspects. Conclusion: There is a need for continuing education for better implementation and assessment of pain, breaking down existing barriers between professionals and patients, which influences a better therapeutic approach.
