Mammography screening every two years is as effective as annual screening
Mammography screening every two years is as effective as annual screening

(March 19, 2013 - Insidermedicine)

From San Francisco – Screening for breast cancer every two years is just as effective as screening annually, according to a report published in JAMA Internal Medicine. Researchers reviewed 14 years of data from mammography facilities, as well as data on over 11,000 breast cancer patients and nearly 1,000,000 healthy controls. Results showed that biennial screening, compared to annual screening, for women 50-74 years old was not linked to increased risk of advanced-stage cancer, regardless of breast density or use of hormone therapy. As well, the cumulative risk of false-positive test results was higher among those undergoing annual mammography. Researchers thus recommend that women aged 50-74 can undergo biennial screening regardless of their breast density.
