Model suggests extending annual mammography screening past age 75 may be cost-effective for some healthy older women

A modeling study found that very small number of deaths averted from breast cancer may be eclipsed by cost and potential harms of overdiagnosis when annual mammography screening is extended past age 75 years. Biennial screening mammography to age 80 years is more cost-effective but the absolute number of deaths averted is small, especially for women with other underlying health conditions. The findings are published in Annals of Internal Medicine.
