WASHINGTON, D.C. --Sen. Lisa Murkowski, R-Alaska, is calling for a hearing to look into how the U.S. Preventive Services Task Force developed recommendations calling for pushing back the age and frequency at which women get screened for breast cancer.

Murkowski, along with 21 other senators from both parties, asked the Democratic chairman and the top Republican on the Senate Committee on Health, Education, Labor and Pensions to conduct the hearing.

"These recommendations, which have been widely criticized by patients and doctors alike, could prove devastating for women at risk for breast cancer," Murkowski wrote in a letter to the two committee leaders. "The American people deserve to know more about how this task force came to its controversial findings."
