Duke University and Hospital are being sued by Betty Eldreth. Eldreth received unnecessary radiation and surgery based on results from an experimental procedure that was performed without her consent. The results indicated Eldreth had cancer, but she was found to not have cancer after the surgery and radiation were complete. Evidence suggests that the experimental procedure was used improperly and this was known some at Duke who failed to stop the practice. This has caused the U.S. House of Representatives Subcommittee on Oversight and Investigations to look into allegations of fraud and conflict of interest in use of the test.
