High-Risk Women Can Rely On Breast MRI Alone For Screening, Study Suggests.

Friday, September 29, 2017

Aunt Minnie (9/29, Yee) reports on a study published in Radiology which shows that women “at high risk of breast cancer who are undergoing annual breast MRI screening can safely discontinue additional screening mammography, thus reducing their exposure to unnecessaryradiation.” Researchers found that among a population of “high-risk women” of 1,977 screening breast MRI scans and 1,957 screening mammograms, “mammography did not detect any cancers that breast MRI missed, and MRI detected three times as many cancers compared to mammography alone.” Another study published in the same October issue presented findings that support that conclusion, specifically, that MRIscreening “meets or approaches the American College of Radiology’s (ACR) BI-RADS benchmarks.”

Research Suggests Annual Screening Mammography Should Begin At Age 40

Thursday, September 28, 2017

Diagnostic Imaging (9/27) reports a study found that “women in their forties comprise 18.8% of all screen-detected breast cancers, suggesting that annual screening mammography should begin at age 40.” The findings were published in the American Journal of Roentgenology. The investigators “concluded that women in their forties had 18.8% of all screen-detected breast cancers, with similar incidences of screen-detected breast cancer between women from 40 to 44 years and those 45 to 49 years.” The “findings support a similar recommendation for both cohorts and the American College of Radiology recommendation of annual screening mammography starting at age 40.” 

Researchers Create New MR Contrast Agent That Can Locate And Differentiate Between Aggressive And Slow-Growing Breast Cancer.

Wednesday, September 27, 2017

DOT Med News (9/26, Fischer) reports that scientists “have created a new MR contrast agent that can locate and differentiate between aggressive and slow-growing, low-risk types of breast cancer at early stages.” According to DOT Med News, “The gadolinium-based agent lights up cancer biomarkers during scans, overcoming the low sensitivity of MR for imaging markers, and produces signals with different shades ofbrightness that contrast aggressive from slow-growing, low-risk types of cancer.” The research was published in Nature Communications.

Breast MR Imaging May Improve Depiction Of DCIS Components Of Invasive Breast Cancers Prior To Surgery, Research Suggests.

Diagnostic Imaging (9/20) reports that research suggests “breast MR imaging improves depiction of ductal carcinoma in situ (DCIS) components of invasive breast cancers before surgery.” The findings were published in Radiology.

Women Still Value Mammography’s Benefits Over Potential “Harms,” Study Suggests.

Monday, September 18, 2017
Aunt Minnie (9/18, Yee) reports researchers surveyed 429 women and found that fewer than 20 percent of respondents “knew about breast cancer overdiagnosis and overtreatment,” and those who did said they do not find information about overdiagnosis and treatment “believable or persuasive.” Rebekah Nagler, PhD, of the Hubbard School of Journalism and Mass Communication at University of Minnesota, said, “Despite increasing dissemination of information about cancer overdiagnosis and overtreatment via both news media coverage and health-related websites, patient awareness remains low.” The findings were published in Medical Care.
