定期的乳房X线检查（mammograms，国人俗称“钼靶”检查）可以尽可能早地发现乳腺癌（说明：最早可以比“手工”检查提前3年发现乳房的微小癌变），从而极大地改善乳腺癌患者的预后，如术后的生存时间、生活质量等。因此，年龄在45岁或更大的女性理应定期接受乳房X线检查！

Why should I have a mammogram?

Regular mammograms are the best tests doctors have to find breast cancer early, sometimes up to three years before it can be felt. When their breast cancer is found early, many women go on to live long and healthy lives.
