People with cancer often feel severe or constant pain. The pain they experience depends on the type of cancer they have, the stage the disease is at, and the therapy they receive. Approximately 25% to 50% of people with cancer complain of pain at the time of diagnosis, and up to 75% of people with cancer complain of pain as the cancer progresses.
Cancer pain can be defined as a complex sensation that reflects both damage to the body and the body's response to the damage. Although doctors agree that controlling cancer pain is a high priority, pain isn't always understood or treated properly. This is often because of unfounded fears about people with cancer becoming addicted to painkillers.
About 85% of people suffering from cancer pain find pain relief through medication therapy. Pain control is extremely important, not only for people suffering from advanced cancer, but also for those whose condition may remain stable for years to come.
