Knowra Cancer pain Cancer pain Cancer pain is pain caused by a tumor, cancer treatment, or related tissue damage. It can be acute or persistent and may arise through several pain mechanisms.
Nociceptive pain : Pain produced when specialized sensory neurons detect actual or threatened tissue damage. Tumor pressure and tissue injury can activate these pain-sensing pathways.
Cancer pain management : The assessment and treatment of pain associated with cancer and its care. This broader practice combines medicines, procedures, rehabilitation, and supportive care.
Pain : An unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage. Cancer pain is one clinical context for this broader human experience.
Chemotherapy-induced peripheral neuropathy : Peripheral nerve damage caused by some chemotherapy medicines, often producing numbness, tingling, or pain. It is a treatment-related source of cancer pain distinct from pain caused directly by a tumor.
Neuropathic pain : Pain caused by a lesion or disease affecting the somatosensory nervous system. Tumor invasion, surgery, or chemotherapy can damage nerves and produce this pain.
Opioid analgesic : A medicine that reduces pain by activating opioid receptors in the nervous system. Opioids are often used for moderate to severe cancer pain with individualized monitoring.
Pain assessment : The systematic evaluation of pain’s intensity, location, quality, timing, and effects. Assessment helps distinguish changing tumor pain from treatment effects and unrelated causes.
Postmastectomy pain syndrome : Persistent pain in the chest, armpit, or arm following breast cancer surgery. It illustrates pain that may persist after the tumor has been removed.
Inflammatory pain : Pain caused by inflammatory signals that sensitize pain-sensing neurons in injured tissue. Tumors and treatment-related tissue injury can release signals that amplify pain.
Radiotherapy : The use of ionizing radiation to damage cancer cells and control tumors. Radiotherapy can relieve pain by shrinking painful tumors or bone lesions.
