A sixty five year old woman named Nancy smoked a pack of cigarettes a day for 45 years. Then one day she began to cough up blood and suffer chest pains which were dull, aching and persistent. Her family doctor sent her for chest X-Rays and the radiologist detected a tumor in her right lung. The biopsy showed that it was cancer. Nancy was prepared for surgery. The surgeon came into the room, cut open Nancy's chest, looked at the golf ball sized tumor, and said, "Well, other than this tumor, she looks fine." The surgeon did not cut out the tumor, he just told his assistant to sew her up. Six weeks later Nancy died.
