乳房攝影（Mammogram）是早期發現乳癌的重要篩檢工具。根據美國預防服務工作小組（USPSTF）與美國癌症協會（ACS）目前的共識，對於 50 至 74 歲、風險平均的女性，建議每兩年進行一次乳房攝影檢查。這項建議是基於臨床實證，旨在平衡早期發現癌症的效益與過度診斷（Overdiagnosis）及偽陽性帶來的心理壓力和不必要侵入性檢查的風險。護理師在提供健康教育時，應強調篩檢頻率需依據個人風險評估及醫師建議進行調整。
Mammography is an important screening tool for the early detection of breast cancer. According to the current consensus of the U.S. Preventive Services Task Force (USPSTF) and the American Cancer Society (ACS), women aged 50-74 years at average risk should undergo screening mammography every 2 years. This recommendation is based on clinical evidence and is intended to balance the benefits of early cancer detection against the risks of overdiagnosis and the psychological stress and unnecessary invasive procedures caused by false-positive results. When providing health education, the nurse should emphasize that the screening interval may need to be adjusted based on individual risk assessment and physician recommendation.
在台灣，國民健康署提供 45 至 69 歲女性每兩年一次免費乳房攝影檢查（二等親內有乳癌家族史者可提前至 40 歲）。美國醫療體系則更強調「共同決策（Shared Decision Making）」，若病人有特殊家族史或高風險因子，醫師可能會建議更頻繁或更早開始篩檢。
