Pain Management in Cancer Patients

Abstract

Pain is always a subjective experience that is influenced by behavioral, biological, and social factors. Timely assessment and proper treatment can significantly reduce the consequences associated with inadequate pain relief. The pathophysiology of the pain that is suffered by cancer patients is overly complex and is thought to be due to various mechanisms involved. It is thought that many of them complain of severe neuropathic pains, which may be due to the ongoing compression, ischemia, and inflammation. In addition to the pain of their metastatic disease, they also suffer from treatment-related pains and procedural/surgical pains. This review article highlights the pathophysiology, and assessment and particularly focuses on the management of pain in cancer patients with different modalities using Oncological, Pharmacological, Non-pharmacological, and Interventional techniques.
