The US Preventive ServicesTask Force (USPSTF) reaffirmed its recommendations to screen
women ages 50-74 for breast cancer every two years stating that the harms of
annual screening outweighed the benefits.
It
also says the decision on frequency of screening should be individualized for
women ages 40-49 based on risk. The
USPSTF found insufficient evidence to recommend for or against screening for women
75 or older.
Several professional societies like the American College of
Radiology and Society of Breast Imaging advocate annual screening mammography
starting at age 40.
The study was presented at the 103th annual meeting of the Radiological Society of North America.
