    if the test comes back negative, it’s wrong only about 3 times out of 10,000,”

    This is a hard one. While this could lead to an increase in the frequency of body scans, it’s being said by a healthcare ceo so I kind of need him to play a game a Luigi’s Mansion before I can listen to him.

      So there-in lies the problem, which is that things like cancer, are already rare. Say there are 6 real instances of cancer in 10,000.
