Mechanisms of cancer pain is discussed in this article. Cancer pain is thought to include three essential pain mechanisms such as noxious, neuropathic and psychological pain mechanism. In the clinical field of cancer pain management, cancer pain is classified into next three categories such as pain caused by cancer mass itself, physiological and biochemical pain associated with malignant tumors and pain caused by the therapies of cancers. Therefore, management of cancer pain should include the strategies which are suitable to each pain mechanism. A pharmacological procedure to diagnose the mechanism of pain, Drug Challenge Test, is thought to be useful in the differential diagnosis of cancer pain.
