Study Finds 3-D mammography Can Improve Breast Cancer Detection

Women that have dense breast tissue are at a higher risk of developing breast cancer since they have more fibrous or glandular tissue compared with women with less dense breasts. Additionally, in women with dense breasts, nodules are harder to detect with standard mammogram technology. Evidence shows that although ultrasound and magnetic resonance imaging have a better response at targeting cancers than mammograms, they present a high rate of false-positive results. This causes further unnecessary biopsies, making these screening modalities less cost-effective. Recently, studies have shown that 3D mammography is an accurate, cost-effective and efficient method for breast cancer detection, demonstrating this method is responsible for a reduction in the number of false-positives, that ultimately are anxiety-inducing. A team of researchers from the Department of Radiology at the Oslo University Hospital in Norway, lead by Per Skaane, M.D., Ph.D., evaluated tomosynthesis (3D mammography) as an encouraging breast cancer screening method that tackles the limitations found in other screening modalities and can additionally provide 3-D assessments. "Tomosynthesis could be
