The majority of people with cancer will experience pain at some time or another. The pain can result from the cancer itself, or from the cancer’s treatment. In addition, some people who have been cured of their cancer can continue to suffer from pain. Although cancer pain is usually treated with medicine, surgery to remove a tumor or radiation therapy to shrink a tumor can be used along with medicine to provide additional pain relief. In most cases, doctors treat cancer pain with pain-relief medicines called analgesics or with non-drug treatments such as physical therapy and rehabilitation, imagery, biofeedback and relaxation techniques. Other treatment options for cancer patients include nerve blocks, which involve the injection of pain medicine into or around a nerve or the spine.
