[Pain and cancer]

Pain is one of the most frequent symptoms encountered in oncology which, regarding its complexity and its effects on quality of life, will be better treated with a multidisciplinary approach, for in and out-patients. The knowledge of the pain syndromes associated with an accurate use of pain medicine provide a rapid control of the symptomatology. A coherent use of opioids, the introduction of new drug delivery systems, and the use of new molecules offer new horizons in the control of cancer pain.
