How frequently does the USPSTF recommend mammography screening for women aged 40 years and older?

The United States Preventive Services Task Force (USPSTF) recommends that women aged 40 years and older undergo mammography screening every 1 to 2 years. This frequency strikes a balance between ensuring adequate screening to catch breast cancer early while also considering potential risks and harms associated with more frequent testing.

The recommendation is based on evidence that regular screenings in this age group can significantly reduce breast cancer mortality by enabling earlier detection of potential issues. By advising screenings every 1 to 2 years, the USPSTF acknowledges that while annual screenings may provide slightly more frequent monitoring, they can also increase false positives and unnecessary procedures, which may lead to anxiety and additional healthcare costs.

In contrast, other options suggest longer intervals or limited screenings, which would not adequately address the need for timely detection of breast cancer in this age group. Thus, the 1 to 2 year interval is seen as the most effective and balanced approach for promoting women's health in regard to breast cancer screening.
