The United States Preventive Services Task Force plays an important role in protecting access to low-cost or free cancer screenings and tests for chronic diseases.

Health Secretary Robert F. Kennedy Jr. is considering removing all 16 members of a highly influential advisory committee that offers guidance about preventive health services, such as cancer screenings, HIV prevention medications or tests for osteoporosis, according to two people familiar with the plan.

The United States Preventive Services Task Force is a group of independent doctors, nurses and public health experts who volunteer to regularly review volumes of the latest scientific research about diseases, such as diabetes, obesity, heart disease and mental health, as well as mammograms for breast cancer.
