* this is not a scientific paper, it an editorial

* it was published in 1999

* in a very sketchy journal

  >development of lung cancer, then I would agree. The 
  >purpose of this article is to emphasize the need to use 
  >language appropriately in both the medical and scientific 
  >literature (the media, as a whole, may be a lost cause).
