Study: Risk Of Radiation-Induced Breast Cancer, Breast Cancer Death Due To Screening Mammograms Is Minimal

Wednesday, November 19, 2014
Diagnostic Imaging (11/19) reports that research published in Acta Radiologica suggests that “the risk of radiation-induced breast cancer and breast cancer death due to mammographic screening is minimal.” Investigators found “that a total lifetime risk of radiation-induced breast cancers per 100,000 women was 10 among those women who were followed from the ages of 50 to 85, for a dose of 2.5 mGy, a latency time of 10 years, and a DDREF of 1.” Meanwhile, “for the same parameter values the number of radiation-induced breast cancer death was one.” 

Adding AB US To Screening Mammography May Lead To Better Cancer Detection

Thursday, November 6, 2014
Diagnostic Imaging reports on a study in the journal Radiology that found “Adding automated breast (AB) ultrasonography (US) to screening mammography increases cancer detection among women with dense breasts.” The study also found “an increase in the number of false-positive test results.”

Increased Breast Density May Improve Radiologists’ Visual Search Process

Wednesday, October 22, 2014
According to a study published in the November issue of the journal Academic Radiology, “increased breast density of a patient seemed to improve the visual search process of experienced radiologists in locating lesions on digital mammography.” Researchers “found for low-density cases, radiologists took about 2.28 seconds to first fixate the lesion when it was overlying the dense area and 8.44 seconds when it was outside,” whereas “for the high-density cases, radiologists took a median time of 7.96 seconds to first fixate the lesion when it was overlying the dense tissue and 12.63 seconds when it was outside.” 

Money Magazine endorses annual screening mammography starting at age forty

American Cancer Society, American College of Radiology, the Society of Breast Imaging and American College of Obstetricians and Gynecologists still recommend getting your first mammogram, an X-ray of your breasts, at 40.

Pan-Canadian Study of Mammography Screening and Mortality from Breast Cancer

Pan-Canadian Study of Mammography Screening and Mortality from Breast Cancer
A Pan Canadian study involving more than 2.7 million women showed a reduction in breast cancer mortality for the screened population. An analysis of 7 out of 12 Canadian screening trials which represented 85% of the population demonstrated a 40% reduction in breast cancer mortality. This study contradicts the paper which reported the 25 year results of the Canadian National Breast Screening Study which followed nearly 90,000 women and no mortality reduction was found.
