Community breast cancer screening comes up short
Performing community-based screening for breast cancer may have no clear effect on reducing the rate of fatalities attributed to the disease, according to a study published in the July 20 issue of the Journal of the National Cancer Institute.

The findings keep alive the debate surrounding breast cancer screening. In the last installment, a randomized controlled trial from Danish researchers showed that screening significantly reduces breast cancer mortality. But the JNCI study argues that most recommendations are based on data produced in carefully controlled studies and not in community-based screening.
Although the investigators at the University of Washington in Seattle observed a 26% reduction in mortality among women at increased risk, they found that figure was statistically insignificant. There was no appreciable association between breast cancer mortality and screening history regardless of age or risk level, they said.
Seven Takeaways from Meta-Analysis of PSMA Radiotracers for Prostate Cancer Imaging
December 1st 2023In a newly published meta-analysis of 24 studies, researchers noted that the PSMA PET radiotracer 18F PSMA-1007 may provide more benefit than 68Ga Ga-PSMA-11 for primary staging of patients with prostate cancer and detection of local lesion recurrence, but also has drawbacks with higher liver uptake and multiple reports of false positive bone lesions.
Study: Regular Mammography Screening Reduces Breast Cancer Mortality Risk by More than 70 Percent
November 30th 2023Consistent adherence to the five most recent mammography screenings prior to a breast cancer diagnosis reduced breast cancer death risk by 72 percent in comparison to women who did not have the mammography screening, according to new research findings presented at the annual Radiological Society of North America (RSNA) conference.
Chest CT Study Shows Higher Emphysema Risk from Combination of Marijuana and Cigarette Smoking
November 28th 2023People who smoke marijuana and cigarettes have 12 times the risk for centrilobular emphysema than non-smokers, according to new computed tomography (CT) research presented at the annual Radiological Society of North America (RSNA) conference.
