Pharmacological Management of Cancer Pain
WHAT YOU NEED TO KNOW:
What do I need to know about cancer pain?
Cancer pain may be short-term or long-term. It may come and go. You may have pain if the tumor damages or blocks tissues, nerves, and blood vessels as it becomes larger. Some cancer cells may produce chemicals that cause pain. Chemotherapy, radiation therapy, or surgery may cause pain. Pain management is an important part of cancer care.
How is the cause of cancer pain diagnosed?
- A pain diary can help your healthcare provider find the cause of your pain. Include anything that makes your pain better or worse. Also include when your pain begins and ends. Bring the pain diary to follow-up visits with your healthcare provider.
- Pain scales help measure the amount of pain you feel. Pain scales may include numbers or faces. Your healthcare provider may ask you to rate the pain on a scale of 0 to 10.
- An x-ray, CT, or MRI may be used to find the cause of your cancer pain. You may be given contrast liquid to help the pictures show up better. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
- Stimulation tests may help find nerves or muscles affected by pain. These tests may include electromyography (EMG), nerve conduction studies, and evoked potential (EP) studies.
Which pain medicines may I need?
- Acetaminophen is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Acetaminophen can cause liver damage if not taken correctly.
- NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
- Narcotic analgesic medicines are used for moderate to severe pain. They may be used to control cancer pain or after surgery and other procedures.
- Anesthetic medicines may be injected in or around a nerve to block pain signals from the nerves.
Which other medicines are used to treat cancer pain?
- Antidepressants may be used to help decrease or prevent the symptoms of depression or anxiety. They are also used to treat nerve pain.
