RALEIGH, N.C.--(BUSINESS WIRE)--Not every breakthrough is positive. Of the approximately 1.4 million new cancer patients in the U.S. each year, more than half experience pain associated with their disease. The patient’s level of pain changes throughout the day, with many patients experiencing two kinds of chronic cancer pain: persistent pain and what is known as “breakthrough pain” (BTP).
While persistent, or continuous, pain can usually be controlled through a patient’s daily pain medication regimen, breakthrough pain literally “breaks through” these therapeutic roadblocks and is not alleviated by regular doses of pain medication.
