Should women with a single first-degree relative with breast cancer begin mammography at age 40? EVIDENCE-BASED ANSWER: Do consider it. A woman with a single first-degree relative (mother or sister) affected by breast cancer has about a 1.5 times higher risk of developing breast cancer and is likely to experience a similar risk-to benefit ratio from beginning mammography at age 40 as an average-risk woman beginning mammography at age 50 (SOR: B, cohort study and modeling study). The US Preventive Services Task Force (USPSTF) recommends consideration be given to starting mammography at age 40 based on individual factors including family history in a first-degree relative (SOR: B, evidence-based guideline), while the American Cancer Society (ACS) suggests all women be given the option of initiating screening at age 40. (SOR: C, consensus guideline).
