How often should women aged 50 and older have a mammography according to USPSTF recommendations?

According to the U.S. Preventive Services Task Force (USPSTF) recommendations, women aged 50 and older should undergo mammography screening every two years. This biennial screening is based on evidence supporting the balance between benefits and potential harms of breast cancer screening in this age group. The USPSTF recognizes that while mammography can significantly reduce breast cancer mortality, especially in older women, the frequency of screening should take into account factors such as individual risk, preference, and the latest evidence on the benefits of screening at different intervals.

The recommendation aims to ensure that women are regularly screened to catch any potential signs of breast cancer early while minimizing the risks associated with over-screening, which can lead to unnecessary anxiety and additional procedures. This interval effectively balances the benefits of early detection with considerations of the risk of false positives and potential overtreatment. Therefore, women should follow the guidance of having mammograms every two years starting at age 50, which aligns with the recommended interval for this group according to the latest guidelines.
