The Washington Post (10/3, McGinley) reports in “To Your Health” that “breast cancer death rates declined” nearly “40 percent between 1989 and 2015, averting 322,600 deaths, the American Cancer Society reported” yesterday in CA: A Cancer Journal for Clinicians. The study indicated “breast cancer death rates increased by 0.4 percent per year from 1975 to 1989.” However, “after that, mortality rates decreased rapidly, for a 39 percent drop overall through 2015.”
TIME (10/3, Park) reports, “In some states, the death rates from breast cancer among white women and black women are equalizing, suggesting that access to screening and treatments are more evenly distributed in those parts of the” US. However, “the data still show that black women have the highest death rates from breast cancer nationally.”
Meanwhile, HealthDay (10/3, Dallas) reports, “The median age for breast cancer deaths is 68, but black patients died younger – at 62, on average.” Also covering the story are Medscape (10/3, Nelson) and Healio (10/3, Leiser).
Aunt Minnie (10/3, Kim) reports that there are “substantial differences around the world in the amount of radiation dose being used for CT scans,” according to a study published online in the American Journal of Roentgenology. Swiss researchers used radiation dose-tracking software to study the amounts in select North American and European medical institutions and found that “CT dose levels measured at California hospitals and from facilities reporting to the American College of Radiology (ACR) Dose Index Registry (DIR) were up to 240% higher than the dose used at their facility, University Hospital Basel.” The piece concludes, “the inconsistency in CT radiation dose used at local neighboring facilities and the wide-ranging differences among distinct registries suggest the need for dose optimization, according to the authors.”
DOT Med News (9/29) reports that research “mobile mammography patients aren’t getting the follow-up imaging they need.” The findings are to be published in the American Journal of Roentgenology.
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.”
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.”
