CISNET Study Finds That Mammography Every Other Year May Be Sufficient for Women with Average Breast Cancer Risk
Please see Hopkins statement regarding these recommendations!
A comprehensive analysis of various mammography screening schedules suggests that biennial (every two years) screening of average risk women between the ages of 50 and 74 achieves most of the benefits of annual screening, but with less harm. The results represent a unanimous consensus of six independent research groups from various academic institutions. Their findings are published in the journal Annals of Internal Medicine.
Researchers from CISNET, the NCI-funded Cancer Intervention and Surveillance Modeling Network, used independent models to examine 20 screening strategies with different starting and stopping ages and intervals. Modeling estimates the lifetime impact (outcomes including benefits and harms) of breast cancer screening mammography. The CISNET models link known data across the course of life and include national data on age-specific breast cancer incidence, mortality, mammography characteristics and treatment effects.
