“Tomosynthesis detects 40% more breast cancers than traditional mammography does, according to a major screening study from Lund University, Sweden. This is the first large-scale study to compare the screening method with regular mammograms. The 3D X-ray technique is also more comfortable for women, as breast compression is halved.
“A total of 7 500 women aged 40-74 took part in the first half of the study, which formed the basis for the findings.
” ‘We see a change as inevitable. Breast tomosynthesis will be introduced, it is just a question of when and on what scale,’ explains Sophia Zackrisson and Kristina Lång, radiologists at Skåne University Hospital in Malmö and researchers at Lund University.
“Breast tomosynthesis is a three-dimensional X-ray technique that makes it easier to detect tumours in breast tissue. The technique works on the same principle as tomography. This means that X-ray images of the breast are acquired from different angles, which can then show multiple thin layers of the breast. This is compared with a traditional mammography, where all the breast tissue is reproduced in a single image, which can hinder the early detection of tumours.”
