Breakthrough pain is relatively common among cancer patients (affects over 50% of patients), particularly those with moderate to severe background pain. Breakthrough pain is one of the most difficult pain syndromes to treat. Breakthrough cancer pain can result from the cancer or cancer treatment, or it may occur during certain activity (e.g. walking, dressing, coughing). it also can occur unexpecte dly, without a preceding incident or clear cause. Persistent and breakthrough pain are distinct components of cancer pain and require separate management.
