Cancer pain refers to the pain experienced by cancer patients as a result of either the tumor pressing on nearby nerves or organs, chemotherapy, radiation therapy, surgery, or other cancer-related treatments. Cancer pain can vary in intensity and severity, and can significantly impact the quality of life for patients. Research in this area focuses on understanding the underlying mechanisms of cancer pain, developing effective treatment strategies, and improving the overall management of pain in cancer patients. This research may involve studying the neural pathways involved in pain transmission, evaluating the efficacy of pain medications and other interventions, and exploring the psychosocial aspects of pain management in cancer patients. Ultimately, the goal of research in this area is to improve pain relief and overall outcomes for cancer patients.
