Definition

"Cancer" refers to any one of a large number of diseases. People with cancer have abnormal cells in their bodies that divide uncontrollably and can destroy normal body tissue. Cancer can spread throughout the body and sometimes causes moderate to severe pain.

Causes

There are several biological reasons you may feel cancer pain:

• Cancer treatment such as surgery, radiation, and chemotherapy
• Scar tissue resulting from surgery or cancer treatment
• A tumor may grow into – or crowd out – organs, nerves, or other parts of the body

Symptoms

Cancer pain usually falls into one of two categories:

• Nociceptive pain – caused by damage to tissue; described as sharp, aching, or throbbing
• Neuropathic pain – caused by actual nerve damage; described as a burning or heavy sensation, or numbness

Diagnosis

Your doctor may diagnose you with cancer pain if:

• Your pain doesn't go away, even when medication is taken as directed
• Side effects are getting in the way of your daily activities/reducing your quality of life
