Summary

• A Professor of Radiology at the Harvard Medical and Founder of the Breast Imaging Division at the Massachusetts General Hospital, Dr. Kopans is an internationally recognized expert in breast cancer detection and diagnosis. He helped found and develop the field that he named "Breast Imaging". He ran a large (35,000 patient) clinical practice as well as an intensive research program that included inventing and developing Digital Breast Tomosynthesis. With more than 250 scientific publications and book chapters he is the single author of a major, 1000 page, textbook entitled “Breast Imaging”, now in its third edition.
  
  He co-chaired the original committee that developed the American College of Radiology Breast Imaging Reporting and Data System (BIRADS) that was based on the reporting system that he developed at the Massachusetts General Hospital.
  
  As a leading expert, Dr. Kopans was invited by the National Breast Screening Study of Canada (now the CNBSS) to review the quality of their mammography revealing that they were “poor to unacceptable” for much of the trials and that the unblinded allocation resulted in an imbalance in the distribution of cancers. His advice that the coordinators be interviewed to determine if there had been nonrandom allocation as the data suggested, was turned down by the PI of the CNBSS. He has joined Canadian experts in calling for the withdrawal of the, scientifically, unreliable results from the CNBSS trials.
  
  His “Springhook Wire” guide, has, for over 40 years directed the safe surgical removal of clinically occult lesions allowing for the early diagnosis of breast cancer cutting the death rate in the U.S. by over 40%.
  
  Dr. Kopans has, repeatedly, exposed scientifically unsupportable arguments being used to try to limit access for women to early detection. His work helped the United States Preventive Services Task Force (USPSTF), in 2024, to, once again, advise women to participate in screening beginning at the age of 40.
