En Espaol (Spanish Version) Approximately one-third of people with cancer have pain. There are different types of cancer pain, all depending on the progression of the disease, its location in the body, and the physical condition of the patient.
Based on the cause of pain, researchers have defined different cancer pain syndromes, including:
- Pain from the tumorTumors can press on bone, nerves, or an organ, resulting in pain.
- Pain related to cancer therapychemotherapy, radiation therapy, and surgery are used to treat cancer.
- Pain unrelated to the cancer or treatmentThis refers to pain (in people with cancer) that has nothing to do with the illness or its treatment (eg, headache, arthritis, muscle strains).

A risk factor is something that increases your chance of getting a disease or condition. Having cancer is a risk factor for cancer pain.
Any type of pain experienced by a cancer patient can be considered cancer pain. The pain may be near or far from the location of the tumor, of varying degrees of intensity, and chronic or intermittent. The pain can be described as pressure, sharp, dull, throbbing, burning, stabbing, and/or achy.
DiagnosisYour doctor will ask about your symptoms and medical history, and perform a physical exam. He or she may also perform tests to determine possible causes of the pain.These may include imaging studies such as CT scan and MRI scans to look for structural problems such as bone fractures and lesions which could cause pain.Other tests such as electromyography (EMG) and nerve conduction velocity (NCV) may be performed to evaluate for a neuropathy, plexopathy, or radiculopathy which may be causing pain. TreatmentTalk with your doctor about the best treatment plan for you. Your plan will depend on the type of pain you are experiencing and how your cancer has been treated. Medications to treat cancer pain include the following: Non-opioidsAcetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen can be used to treat mild to moderate cancer pain. OpioidsWeak opioids (eg, codeine) or strong opioids (eg, morphine) are often used to treat moderate to severe cancer pain. Other MedicationsAntidepressants, anti-epileptics, and steroids may be effective in relieving certain types of cancer pain. These types of medication may be of benefit if the pain is thought to be either neuopathis or central (related to the central nervous system).
Radiation TherapyRadiation therapy can be used to relieve bone pain, as well as pain caused by tumors compressing other structures. PreventionUsually, cancer pain is difficult to avoid. To manage your pain, the best thing you can do is talk with your doctor about any pain you are experiencing. He or she can help you devise a plan for managing your pain.
