Minnesota doctors now must report dense breast tissue on mammograms

Thursday, August 28, 2014
Minnesota mandated as of Aug. 1 that” physicians “notify women if their mammograms discover dense breast tissue, which can mask the presence of a tumor on an X-ray.” The Star Tribune points out that “letters with mammogram results started going out from Mayo Clinic this month with...tissue density” information, but “the response has been so mild that the clinic’s director, Dr. Karthik Ghosh, wonders if women are reading beyond the first sentence indicating a negative test result.” 

Study: Mammography False Alarms Linked To Later Tumor Risk

Danish researchers as saying that, for unknown reasons, women whose mammogram screenings generate “false positives” are at a higher risk of being diagnosed with breast cancer in the years that follow. The University of Copenhagen study, published in Cancer Epidemiology, attempted to determine how much, if any, of the extra risk is due to doctors missing the cancer the first time they scrutinized the seemingly dire mammogram findings, but such errors explained just a small percentage of the increased risk, said lead author and epidemiologist My von Euler-Chelpin. The researcher said it’s likely a smaller percentage of American women would have a heightened risk for breast cancer after a false-positive test because the US has a higher rate of false positives than Denmark. 

Study: Recurring Breast Cancer Detected By MRI, Missed By Other Modalities

Friday, August 22, 2014
A study published in Radiology suggests that recurring breast cancer missed by ultrasound and mammography can be detected by single-screening MRI. The study’s authors suggested that “it may be appropriate to recommend screening MRI imaging in women (younger than 50) with a personal history of breast cancer.” 

Combining DBT Plus 2D Mammography May Improve Radiologists’ Performance

Thursday, August 21, 2014
A study published in the September issue of Academic Radiology, “the clinical performance of radiologists improves when digital breast tomosynthesis (DBT) is combined with conventional 2D full-field digital mammography (FFDM) for breast cancer screening.” For the study, researchers looked at “10,878 screening exams conducted between May 2011 and January 2012 with both tomosynthesis and FFDM.” The study authors found that “radiologists have lower recall rates and their cancer detection rates are higher when both technologies are used.”

DBT Combined With FFDM May Improve Breast Cancer Detection

Thursday, August 14, 2014
Health Imaging reports that according to a study published in the September issue of the journal Academy Radiology, “combining digital breast tomosynthesis (DBT) with full field digital mammography (FFDM) cut recall rates by 35 percent and dramatically improved breast cancer detection.” The study revealed that “the rate of invasive breast cancer detection was 66 percent higher when using DBT together with FFDM than when using only FFDM.”
