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.
Aunt Minnie (9/14, Yee) reports that a new study shows that mobile mammography programs are “a move in the right direction, but more work needs to be done to better assist women who make use of mobile mammography,” including to ensure follow-up. At team led by Dr. Madelene Lewis of the Medical University of South Carolina in Charleston found that its mobile program was “only somewhat successful” in addressing the issues of getting underserved women screened. The study looked at “1,433 screening mammography exams performed in a mobile unit in 2014, and 1,434 exams performed at the university’s cancer center during the same year.” Lewis’ team “recorded associations between the two locations and characteristics such as health insurance, race, marital status, geographic area, adherence to screening guidelines, and recall rates.”
HealthImaging (8/30, Walter) reports that research suggests “starting annual screening mammography for breast cancer at age 40 helps detect a significant number of cancers.” The article points out that “some advocacy groups, including the American College of Radiology, recommend starting annual screening at age 40, while other groups, such as the U.S. Preventive Services Task Force (USPSTF), recommend women wait and begin biennial screening at age 50.” The study was published in the American Journal of Roentgenology.
