Breast Cancer Screening, 2015 Guideline Update From the American Cancer Society.

All the recommendations apply to women at average risk, meaning those with no personal history of breast cancer, no genetic susceptibility to breast cancer, and no history of chest radiation treatment.
The 2015 Guideline recommends:
Women ages 40-44 can begin annual screening mammography
Women ages 45-54 should undergo annual screening mammography
Women ages 55 and older can transition to every-other-year screening OR continue annual screening mammography
Women should continue screening mammography as long as their overall health is good and they have a life expectancy of 10 years or longer
Women at any age should not rely on breast examination for breast cancer screening

Síntesis de la evidencia:
Estimates of the cumulative lifetime risk of false-positive examination results are greater if screening begins at younger ages because of the greater number of mammograms, as well as the higher recall rate in younger women. The quality of the evidence for overdiagnosis is not sufficient to estimate a lifetime risk with confidence. Analysis examining the screening interval demonstrates more favorable tumor characteristics when premenopausal women are screened annually vs biennially. Evidence does not support routine clinical breast examination as a screening method for women at average risk.
