A bill just passed by the U.S. Senate was a decade in the making.  The bill directly affects what happens when people go in for genetic testing.  Genetic testing is used to determine whether someone is predisposed to cancer, diabetes, or varying illnesses in their genetic makeup.  Many doctors say it's a great way to prevent the illness from happening in the first place, a preventative measure.  Health insurance companies were using the test results to hike up the insurance rates, cancel or drop people.  The new bill would ban discrimination on the basis of genetic testing.  People have cited in the past that they did not want screening for certain illnesses such as cancer because of health insurance problems.
