In 2000, the US FDA approved digital mammography technology. Studies suggested the new technology was equivalent to older film technology in detecting cancer. There was also limited evidence that digital imaging might be more specific, meaning that it would reduce the number of callbacks for positive findings. Many also believed that the newer “improved” digital technology might find more disease and lead to fewer interval cancers (cancers diagnosed between scheduled screenings).

数字化癌症筛查时代的过度诊断。

2000年，美国FDA批准了数字乳腺X线摄影技术。研究表明，新技术在检测癌症方面等同于较老的胶片技术。也有有限的证据表明数字成像可能更具体，这意味着它将减少积极发现的回调次数。许多人还认为，更新的“改进的”数字技术可能发现更多的疾病，并导致更少的间隔癌症（在定期筛查之间诊断出癌症）。
