How often should women ages 50-74 have a mammogram according to current guidelines?

Women aged 50-74 are recommended to have a mammogram every 2 years according to current guidelines from organizations such as the U.S. Preventive Services Task Force (USPSTF). This screening interval balances the benefits of early breast cancer detection with the potential risks of overdiagnosis and unnecessary treatments that could arise from more frequent screening. The evidence suggests that biennial mammography maintains a high level of efficacy in identifying breast cancer while minimizing harm and is particularly appropriate for this age group where the incidence of breast cancer increases. Regular screenings within this timeframe allow for timely detection while ensuring that the potential harms associated with more frequent screenings are avoided.
