Cancer pain management in the elderly.

The prevalence of cancer rises with advancing age, and pain is a common complaint of those with cancer. The elderly, especially those older than 85, are at risk for undertreatment of pain. Despite multiple barriers, assessment difficulties, and an increased risk of side effects with opioids, cancer pain can be effectively managed in this population. The quality of life of elderly patients with cancer depends on good symptom management, the appropriate use of analgesics, and prevention of opioid-related side effects.
