Bad ! Doctor!

    My life of late has been spent, for too many hours, in searching the internet for bits and pieces of information which may eventually be of help.
   Interspersed with medical lore are the often poignant slice-of-life stories that people post for their own personal reasons. As Kathie Lee Gifford has so often proclaimed, and sang, "Everyone has a story." And mostly we agree and sympathize, and then forget.
   But every once in a while, a story resonates and sticks in my mind. Here is one such:
           A man brought his mother to the hospital for a minor procedure. That  was  successfully accomplished. However, before discharge, he was informed that one of the routine tests had turned up an unrelated concern, a shadow or what the doctor called a scar. So  his mother was to remain in the hospital while more tests were performed. She underwent the testing and was told the results would take a while.  The family was in agony waiting: was it cancer or just a benign cyst or such?
    Soon after, a doctor arrived and told then she was being discharged. The family was at first elated, thinking that meant the "scar" was not a cancer. No, the doctor told them, the results were not yet in; she was being discharged pending whatever the next step of her diagnosis would be.
   Do you think it's cancerous, they asked. The doctor replied, "If it looks like a duck and quacks like a duck and walks like a duck, it's a duck."
