Professor Boyages rejects claim physical exams reduce mortality on par with mammograms
However, the research has been criticised by one of the pioneers of breast cancer screening in Australia, Professor John Boyages, who said the results do not support abandoning Australia’s recommended bi-annual mammography program for women aged 40 and older.
In the study, 89,835 women aged 40–59 years were randomly assigned to two groups: the first received annual mammograms and physical breast examinations between 1980–85.
