| The first 150 words of the full text of this article appear below. |
Pain is universal, but cancer pain is particularly vicious. "Cancer patients have a bond that surpasses a healthy persons understanding," prostate cancer patient Cornelius Ryan, a prominent historian, wrote in his journal. "The presence of fear and the agony of pain are transmitted without words ... . My young friend [with lung cancer] wanted to die. [She] was being crucified by pain she could no longer endure. Now she is one more statistic."* The following year Ryan, in constant agony from bone metastases to his hips and legs, also died from his cancer.
While acknowledging the severity of cancer pain, doctorsuntil a few years agodid not view it as fundamentally different, in terms of neurophysiology, from other kinds of pain. Cancer pain was thought to be caused by the growing tumor mass compressing or infiltrating soft tissue, pressing on peripheral nerves, and sometimes cutting off blood flow to defined areas
