The new recommendation, women should start screening for breast cancer at age 40
Public health experts suggest that women at higher risk of breast cancer start screening at age 40 to reduce the risk of dying from the disease.
The proposal is an update of the 2016 recommendation, in which the task force recommended that biannual mammograms begin at age 50.
Some groups, such as the American Cancer Society, have already recommended that women start mammograms in their 40s.
"Our new recommendation suggests that women start mammography screening for breast cancer at age 40 and screen every other year until age 74," said Dr. Wanda Nicholson, a senior associate dean and professor at George Washington University.
The USPSTF, a group of independent medical experts whose recommendations help doctors make decisions and influence health insurance plans, released a proposed update to new breast cancer screening guidelines on Tuesday.
The recommendation is not final, but will be open for public comment until June 5.
