          Belgian Researchers Discover Way to Block Cancer Metastasis

   Cancer remains one of the deadliest diseases, despite many new methods
   to combat it. Modern medicine has treatments to prevent the growth of

   the body. A team of Belgian scientists says it has found a way to
   prevent that process. Zlatica Hoke has more.
