Screening mammography has been shown to reduce breast cancer mortality. Both film-screen mammography and xeromammography are highly sensitive and specific. Mammography accreditation programs assure physicians and patients that a facility provides mammography of the highest quality, using the lowest possible radiation dose. Mammographic signs of early cancer include a small mass, calcifications, architectural distortion and a neodensity. Dense tissue may result in a false-negative examination even when a cancer is palpable, with adverse effects if biopsy is delayed.
乳腺钼靶筛查已被证明可降低乳腺癌死亡率。屏-片乳腺钼靶摄影和干板乳腺摄影都具有很高的敏感性和特异性。乳腺钼靶认证项目向医生和患者保证，某机构能以尽可能低的辐射剂量提供高质量的乳腺钼靶检查。早期癌症的钼靶征象包括小肿块、钙化、结构扭曲和新密度影。致密组织即使在可触及癌症时也可能导致假阴性检查结果，若活检延迟则会产生不良影响。
