You are a family physician caring for a healthy 60-year-old woman.

For an otherwise healthy 60-year-old woman, screening mammography every 2 years provides the greatest proven population-health benefit among the listed options. MCCQE prevention objectives emphasize selecting screening that meaningfully reduces morbidity and mortality in the target age group. Breast cancer screening with mammography in women aged approximately 50–74 has evidence for earlier detection and reduction in breast-cancer mortality, and biennial screening balances benefit with harms (false positives, overdiagnosis) better than annual screening.

Annual cervical cytology is not recommended for average-risk women; screening intervals are longer (and discontinuation is generally considered after adequate prior screening at older ages). Bone densitometry is typically initiated later (commonly at 65) for average-risk women, with earlier testing reserved for additional risk factors. Routine annual fasting lipids and annual fasting glucose are not the most useful universal interventions in a healthy person; testing frequency is risk-based rather than yearly for all. Therefore, biennial mammography is the best choice for highest preventive value in this patient.
