The US Preventive Services Task Force (USPSTF) is the body doing that meta-analysis and writing recommendations. The recommendations are for general patients (high-risk patients should be identified and guided by their doctors), and are based on how much the screening/prevention will extend or improve patients' lives. The USPSTF explicitly does not consider monetary cost.
