(HealthDay)—New recommendations have been developed for breast cancer screening based on a life-years-gained model; the American Society of Breast Surgeons (ASBrS) official statement was published online May 3.

The guideline recommendations state that women age >25 years should undergo formal risk assessment for breast cancer. Yearly screening mammography should be initiated at age 40 years among women with an average risk for breast cancer. Women with higher-than-average risk should undergo yearly screening mammography and be offered yearly supplemental imaging, with initiation based on risk. When life expectancy is less than 10 years, screening mammography should cease.

The recommendations vary based on individual risk. Average-risk women should start annual mammography at age 40 years and should consider supplemental screening if they have increased breast density. Women with hereditary susceptibility from pathogenic mutation carrier status or with prior chest wall radiation should undergo annual magnetic resonance imaging at age 25 years and start annual mammography at age 30 years. Women with a predicted risk >20 percent or a strong family history should undergo annual mammography and have access to supplemental imaging starting at age 35 years.
