A recent article in the Journal of the American College of Radiology by MSK clinicians determined that second opinions frequently change the interpretation of diagnostic breast imaging. As reported by HealthImaging.com, a second opinion prevented five percent of patients from receiving unneeded surgery and resulted in a new cancer diagnosis for four percent of the 147 patients included in the study. In total, second opinions led to a change in interpretation of the diagnostic imaging 51% of the time, including both downgrades and upgrades to breast lesions.
