[Treatment of pain in the oncology patient]

Pain is a symptom with a high prevalence in patients with cancer and causes an important deterioration in their quality of life. With the measures laid out by the WHO in 1986, which divides the different therapeutic options available in three ascending steps, pain can be controlled in a high percentage of cases. Those patients who are difficult to control with these measures can benefit from the application of neuromodulation techniques by experts in the treatment of chronic pain. The correct employment of the different medicines (non-steroidal anti-inflammatory medicines, opiates and coadjuvants), knowledge of the secondary effects, loss of fear in the face of opiates and knowledge of the different algic syndromes associated with the oncology patient, must be accompanied by a suitable evaluation of the pain according to the different scales, both in the phase of the treatment's initiation and in the follow-up of the patient.
