Dr. Barnett Kramer, a member of the Lisa Schwartz Foundation for Truth in Medicine and former director of the National Cancer Institute’s Department of Cancer Prevention, fears that the tests will never be effective. Once that happened, he said, “It’s hard to play the bell.”

“I hope we’re not halfway through a nightmare,” said Dr. Kramer.
