根據美國預防服務工作組(USPSTF)指引,50-74 歲女性建議每兩年進行一次乳房攝影篩檢。此篩檢能有效降低乳癌死亡率。雖然部分機構建議 40 歲開始,但標準篩檢策略多集中於此年齡區間,且應與醫師討論個人風險。
The USPSTF recommends biennial screening mammography for women aged 50 to 74 years. This interval effectively balances the benefits of early detection with the risks of overdiagnosis, making it the standard guideline for this age group.
