A new study suggests that Dense Breast Notifications (DBNs) have achieved partial success in informing women about their breast density, with higher rates of notification and discussions with providers in states with mandated DBN laws. However, the study also found disparities in knowledge and awareness among women of different race/et...
Researchers developed two new mammogram-based measures of risk, combining them to predict breast cancer risk more effectively than known genetic and breast density factors. The new measures could improve screening, reduce mortality, and make it less stressful for women.
A new study by MIT scholars suggests that mammogram screening may be more effective for targeted testing, rather than age-based recommendations. Women who start getting mammograms at age 40 are found to be healthier and less likely to have cancer, making targeting higher-risk groups a potential solution.
