Much of the pain related to metastatic breast cancer is due to the cancer itself.  A tumor can put pressure on nerves or the spinal cord, causing injury and pain.  This pain is often described as a sharp, tingling, burning or shooting feeling (neuropathic pain).  Tumors can also cause pain if they spread to organs (such as the liver) or other tissues.  This pain may feel sharp, aching, cramping or gnawing (Visceral pain).  When pain is caused by pressure from a tumor, the tumor itself is often treated.  Surgery, chemotherapy or hormone therapy may be used to shrink the tumor so it no longer presses against nerves, the spinal cord or other organs or tissues.  Surgery can also be used to prevent or control problems such as a blockage in the bowel.  Neuropathic pain can be treated with medications.  If needed, an anesthesia pain specialist can sometimes inject an anesthetic (to relieve pain) and steroid (to reduce swelling) drug combination into or around a nerve to block pain.  In some cases, this drug combination is injected into the fluid around the coverings of the spinal cord or into the spinal fluid itself to block the pain.  It may also be given by vein (through an IV).
