Oncological pain is considered a public health problem in Brazil and in the rest of the world because the investment with hospital admissions of patients without improvement in their quality of life is high. Based on studies that show that one of the major problems to be faced by the health systems of the countries is related to the training of professionals to care for PODC, the present review study was proposed to synthesise the main nursing interventions to control cancer pain in order to fill the gap in assistance to PODC, offering dignified care. Regarding the importance of professional training for pain control, studies show that nursing professionals have little knowledge about patients' pain management, which contributes to patients experiencing pain unnecessarily. The misinformation of professionals involved in the care of patients with cancer pain can lead to ineffective pain assessment.
